Title:Environmentally stable Mn-doped CsPbX3@CsPb2X5 core-shell materials with efficient energy transfer
Author Full Names:Zhang, Chen(1); Xu, Luxia(2); Wang, Minqiang(1); Da, Zheyuan(1); Shi, Jindou(1); Wang, Junnan(1); Yao, Qing(1); Tian, Jinshou(2); Gaponenko, Nikolai V.(3); Xu, Youlong(1)Source Title:Journal of Materials Chemistry CLanguage:EnglishDocument Type:Journal article (JA)Abstract:Mn(ii)-doped cesium lead halide perovskite (CsPbX3 (X = Cl, Br, I)) quantum dots (QDs) have attracted a lot of attention from researchers attributed to their bright orange light emission. However, defects such as inefficient energy transfer and instability have hindered the commercial application of the material. Here, we propose a convenient core-shell coating strategy to epitaxially grow a CsPb2X5 shell on Mn-doped CsPbX3 surfaces by controlling the reaction time and precursor ratio. Meanwhile, density-functional theory (DFT) calculations indicate that a typical type-I heterojunction is formed between the CsPb(Cl/Br)3 cores and the CsPb2(Cl/Br)5 shell, which improves the energy transfer efficiency from an exciton to Mn2+. The obtained Mn-doped CsPb(Cl/Br)3@CsPb2(Cl/Br)5 core-shell materials exhibit enhanced optical properties and excellent water/thermal stability. Subsequently, the white light-emitting diode prepared from the composites shows a high luminescence efficiency of 127.21 lm W−1, and the PL intensity is still maintained above 95% after 24 h of continuous operation. © 2024 The Royal Society of Chemistry.Affiliations:(1) Electronic Materials Research Laboratory, Key Laboratory of the Ministry of Education, International Center for Dielectric Research, Shannxi Engineering Research Center of Advanced Energy Materials and Devices, Xi’an Jiaotong University, Xi’an; 710049, China; (2) Xi’an Institute of Optics and Precision Mechanics, CAS, Add: NO. 17 Xinxi Road, New Industrial Park, Xi’an Hi-Tech Industrial Development Zone, Shaanxi, Xi’an; 710119, China; (3) Belarusian State University of Informatics and Radioelectronics, P.

Title:Mathieu ray-wave structured light with self-healing elliptical accelerating vortices
Author Full Names:Wei, Wenjun(1); Tang, Miaomiao(1); Zhang, Hao(1); Tai, Yuping(1,2); Shen, Yijie(3,4); Li, Xinzhong(1,2)Source Title:Optics LettersLanguage:EnglishDocument Type:Journal article (JA)Abstract:Ray-wave structured vortex beams have attracted increasing attention due to their unique spatial geometric coupling to control complex orbital angular momentum (OAM). Still, current models were constrained by circular symmetry with limited modulation freedom. Herein, we propose a generalized class of ray-wave light fields called Mathieu geometric modes (MGMs) fulfilling the form of a stationary coherent state but based on a set of helical Mathieu modes (HMMs), in which geometrically tunable elliptical accelerating vortices are obtained by tuning their eccentricity-related parameters. MGMs also possess intriguing properties of coordinate transformation, self-healing, and multilayer tunable angular acceleration upon propagation. MGMs have higher degrees of freedom to control spatial accelerating vortices, paving the way for higher-dimensional optical tweezers and complex particle manipulation. © 2024 Optica Publishing Group.Affiliations:(1) School of Physics and Engineering, School of Chemistry and Chemical Engineering, Henan University of Science and Technology, Luoyang; 471023, China; (2) State Key Laboratory of Transient Optics and Photonics, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi’an; 710119, China; (3) Centre for Disruptive Photonic Technologies, School of Physical and Mathematical Sciences, The Photonics Institute, Nanyang Technological University, Singapore; 637371, Singapore; (4) School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore; 639798, SingaporePublication Year:2024Volume:49Issue:19Start Page:5507-5510DOI Link:10.1364/OL.534222数据库ID(收录号):20244117178443 -

Title:Multispectral Image Quality Improvement Based on Global Iterative Fusion Constrained by Meteorological Factors
Author Full Names:Shi, Yuetian(1,2); Fu, Bin(3); Wang, Nan(1,2); Chen, Yaxiong(4); Fang, Jie(5,6)Source Title:Cognitive ComputationLanguage:EnglishDocument Type:Journal article (JA)Abstract:It has been proven that the refractive index is related to meteorological parameters in physics. The temperature changes the atmospheric and lens refractive indices, resulting in image degradation. Image restoration aims to recover the sharp image from the degraded images. It is also the basis of many computer vision tasks. A series of methods have been explored and used in this area. Sometimes, meteorological factors cause image degradation. Most of the existing image restoration methods do not consider meteorological factors’ influence on image degradation. How meteorological factors affect image quality is not yet known. A multispectral image dataset with corresponding meteorological parameters is presented to solve the problem. We propose a novel multispectral image restoration algorithm using global iterative fusion. The proposed method firstly enhances image edge features through spatial filtering. Then, the Gaussian function is used to constrain the weights between each channel in the image. Finally, a global iterative fusion method is used to fuse image spatial and spectral features to obtain an improved multispectral image. The algorithm explores the impact of meteorological factors on image quality. It considers the impact of atmospheric factors on image quality and incorporates it into the image restoration process. Extensive experimental results illustrate that the method achieves favorable performance on real data. The proposed algorithm is also more robust than other state-of-the-art algorithms. In this paper, we present an algorithm for improving the quality of multispectral images. The proposed algorithm incorporates the influence of meteorological parameters into the image restoration method to better describe the relationship between different spectral channels. Extensive experiments are conducted to validate the effectiveness of the algorithm. Additionally, we investigate the impact of near-surface meteorological parameters on multispectral image quality. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Affiliations:(1) Key Laboratory of Spectral Imaging Technology CAS, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Shaanxi, Xi’an; 710119, China; (2) University of Chinese Academy of Sciences, Beijing, Beijing; 100049, China; (3) SenseTime Researchs, Guangdong, Shenzhen; 518000, China; (4) School of Computer and Artificial Intelligence, Wuhan University of Technology, Hubei, Wuhan; 430000, China; (5) School of Telecommunication and Information Engineering, Xi’an University of Posts and Telecommunications, Shaanxi, Xi’an; 710119, China; (6) Corporation of Shaanxi Wukong Clouds Information and Technology, Shaanxi, Xi’an; 710119, ChinaPublication Year:2024Volume:16Issue:1Start Page:404-424DOI Link:10.1007/s12559-023-10207-7数据库ID(收录号):20234314934471 -

Title:Tunable band-stop fiber filter based on laser-induced graphene metamaterial in THz frequency
Author Full Names:Tian, Ziping(1); Luo, Zhenyang(1); Lv, Xianpeng(1); Xie, Manyan(1); Peng, Gangding(2); Kong, Depeng(3); Lu, Huihui(4); Guan, Heyuan(4)Source Title:Optics ExpressLanguage:EnglishDocument Type:Journal article (JA)Abstract:As an important device in the application of terahertz (THz) technology, a THz filter has broad application prospects in the fields of THz communication, imaging, and sensing. In this paper, a THz filter based on grating structure laser-induced graphene (LIG)/ side polishing terahertz fiber composite structure is proposed. In the experiment, we achieved the maximum Q factor of 23.83 at the central resonant frequency of 0.715 THz. By modifying the grating structure, a tunable operational span of 269 GHz was achieved, along with a tunable range of 21 GHz through laser stimulation. In testing, we found that LIG materials prepared with circular filling are more sensitive to relatively high-power pump lasers, while LIG samples prepared with line filling exhibit better linear response to laser power. Furthermore, the compact and highly integrated nature of the device suggests its broad potential utility in the realm of THz frequency selection. © 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.Affiliations:(1) Guangdong Provincial Key Laboratory of Optical Fiber Sensing and Communications, Department of Optoelectronic Engineering, Jinan University, Guangzhou; 510632, China; (2) School of Electrical Engineering and Telecommunications, University of New South Wales, Sydney; NSW; 2052, Australia; (3) Key Laboratory of Transient Optics and Photonics, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Shaanxi, Xi’an; 710119, China; (4) Key Laboratory of Optoelectronic Information and Sensing Technologies of Guangdong Higher Education Institutes, Jinan University, Guangzhou; 510632, ChinaPublication Year:2024Volume:32Issue:14Start Page:24251-24261DOI Link:10.1364/OE.527472数据库ID(收录号):20242916703870 -

Title:Research on subsurface damage mechanism and suppression method of ultrasonic vibration–assisted grinding of sapphire components under extreme service environment
Author Full Names:Sun, GuoYan(2); Zhang, Wanli(1,4,5); Wang, JianYong(3); Ding, JiaoTeng(2); Wang, Bo(1,4,5); Shi, Feng(1,4,5)Source Title:International Journal of Advanced Manufacturing TechnologyLanguage:EnglishDocument Type:Journal article (JA)Abstract:Single-crystal sapphire (α-Al2O3) has a wide range of applications in a variety of extreme environments due to its excellent mechanical and chemical properties as well as its stability under extreme service conditions. In addition, sapphire is a hard and brittle material, which makes it difficult to avoid the introduction of subsurface damage during processing, and the existence of a subsurface damage layer seriously affects the performance of the optical system. Therefore, this study focuses on the mechanism of subsurface damage in sapphire grinding, the suppression of damage depth, and the accurate and fast prediction of damage depth. A subsurface damage model for ultrasonic vibration–assisted grinding of sapphire was established by combining ultrasonic vibration single abrasive grain kinematics and dynamics analysis. The mechanism of ultrasonic vibration–assisted grinding was investigated by combining force and acoustic emission (AE) signals. And the effects of ultrasonic vibration–assisted grinding on the surface quality, subsurface damage form, and depth were analyzed. A comprehensive prediction model of SSD based on surface roughness (Sz) was established by combining indentation fracture mechanics and Gaussian process regression. Finally, by analyzing the influence law of each process parameter on the subsurface damage depth (SSD), the grinding process parameters were optimized, and the subsurface damage suppression strategy was proposed. This study provides theoretical guidance for the high-efficiency and low-damage grinding of sapphire. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2024.Affiliations:(1) College of Intelligence Science and Technology, National University of Defense Technology, 109 Deya Road, Changsha; 410073, China; (2) Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi’an; 710119, China; (3) Luoyang Institute of Electro-Optical Equipment, AVIC, Luoyang; 471009, China; (4) Laboratory of Science and Technology on Integrated Logistics Support, College of Intelligence Science and Technology, National University of Defense Technology, 109 Deya Road, Changsha; 410073, China; (5) Hunan Key Laboratory of Ultra-Precision Machining Technology, Changsha; 410073, ChinaPublication Year:2024Volume:135Issue:5-6Start Page:2215-2242DOI Link:10.1007/s00170-024-14491-x数据库ID(收录号):20244317254246 -

Title:Site-Selective Synthesis of Bilayer Graphene on Cu Substrates Using Titanium as a Carbon Diffusion Barrier
Author Full Names:Song, Qiyang(1); Zhang, Youwei(1,2); Chen, Qiao(1); Wu, Su(1); Yan, Xin(3); He, Kai(3); Gao, Guilong(3); Chen, Qiao(4); Wang, Shun(1)Source Title:ACS Applied Materials and InterfacesLanguage:EnglishDocument Type:Journal article (JA)Abstract:Chemical vapor deposition (CVD) is a widely used method for graphene synthesis, but it struggles to produce large-area uniform bilayer graphene (BLG). This study introduces a novel approach to meet the demands of large-scale integrated circuit applications, challenging the conventional reliance on uniform BLG over extensive areas. We developed a unique method involving the direct growth of bilayer graphene arrays (BLGA) on Cu foil substrates using patterned titanium (Ti) as a diffusion barrier. The use of the Ti layer can effectively control carbon atom diffusion through the Cu foil without altering the growth conditions or compromising the graphene quality, thereby showcasing its versatility. The approach allows for targeted BLG growth and achieved a yield of 100% for a 10 × 10 BLG units array. Then a 10 × 10 BLG memristor array was fabricated, and a yield of 96% was achieved. The performances of these devices show good uniformity, evidenced by the set voltages concentrated around 4 V, and a high resistance state (HRS) to low resistance state (LRS) ratio predominantly around 107, reflecting the spatial uniformity of the prepared BLGA.

We prepared two-layer HfS3 nanosheets and carried out experiments to study their nonlinear saturable absorption properties. The results showed that the two-layer HfS3-based saturable absorber exhibited a modulation depth of 16.8%. Additionally, we conducted theoretical calculations using first principles to estimate the structural and electronic band properties of the two-layer HfS3 material. Furthermore, we utilized the two-layer HfS3 materials as SAs in an erbium-doped fiber cavity to generate mode-locked laser pulses. We measured a repetition frequency of 8.74 MHz, a pulse duration of 540 fs, and a signal-to-noise ratio of 77 dB. Overall, our findings demonstrate that the two-layer HfS3 material can serve as a reliable saturable absorber, possessing properties comparable to currently used two-dimensional materials. This expands the application fields of HfS3 materials and highlights their potential for advanced optoelectronic devices. © 2024 Optica Publishing Group.Affiliations:(1) School of Science, Xi’an University of Posts and Telecommunications, Xi’an; 710121, China; (2) Shaanxi Provincial Center for Regenerative Medicine and Surgical Engineering, First Affiliated Hospital, Xi’an Jiaotong University, Xi’an; 710061, China; (3) State Key Laboratory of Transient Optics and Photonics, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences (CAS), Shaanxi, Xi’an; 710119, China; (4) State Key Laboratory of Information Photonics and Optical Communications, School of Science, Beijing University of Posts and Telecommunications, Beijing; 100876, ChinaPublication Year:2024Volume:49Issue:5Start Page:1293-1296DOI Link:10.1364/OL.513573数据库ID(收录号):20241015683562 -

Title:Differentiable design of a double-freeform lens with multi-level radial basis functions for extended source irradiance tailoring
Author Full Names:Tang, Haisong(1,2); Li, Haoran(1,2); Feng, Zexin(1,2); Luo, Yi(3); Mao, Xianglong(4)Source Title:OpticaLanguage:EnglishDocument Type:Journal article (JA)Abstract:Freeform optics are key for generating prescribed illumination patterns from given sources, which are crucial for solid-state lighting and machine vision illumination. There is an increasing demand for compact freeform optics, which presents a substantial challenge for current design methods since the source dimensions must be considered. Most current extended-source design methods, although requiring profound knowledge of optics and mathematics, focus on the modest goal of obtaining uniform irradiance distributions. We address a more challenging design problem of generating an irradiance distribution of arbitrary shape through a double-freeform lens that can fully encompass the extended source. We propose a differentiable design method whose uniqueness lies in the representation of the double-freeform surfaces using multi-level spherical radial basis functions, which has a natural link to a multi-scale optimization technique. In addition, we employ a sequential unconstrained minimization technology complemented with Lagrange multipliers that add key feasibility constraints on lens shape and size. The proposed method is flexible, general, and efficient in designing highly compact freeform lenses for generating both simple and complex irradiance distributions, as demonstrated through the design examples. This could enable a universal solution to the extended-source design problem. © 2024 Optica Publishing Group.Affiliations:(1) Beijing Engineering Research Center of Mixed Reality and Advanced Display, School of Optics and Photonics, Beijing Institute of Technology, Beijing; 100081, China; (2) MOE Key Laboratory of Optoelectronic Imaging Technology and Systems, Beijing Institute of Technology, Beijing; 100081, China; (3) Beijing National Research Center for Information Science and Technology, Department of Electronic Engineering, Tsinghua University, Beijing; 100084, China; (4) The New Technology Laboratory of Space Photon Information, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Shaanxi, Xi’an; 710119, ChinaPublication Year:2024Volume:11Issue:5Start Page:653-664DOI Link:10.1364/OPTICA.520485数据库ID(收录号):20242116151703 -

Title:Advanced lead-free double perovskites/silica hybrid nanocrystals for highly stable light-emitting diodes

Recent interest has converged on lead-free double perovskites (DPs), renowned for their optical properties mirroring those of traditional lead-based counterparts and superior atmospheric stability. However, these materials encounter significant fluorescence degradation in thermal environments, a challenging scenario given the high temperatures endemic to the surfaces of optoelectronic devices during prolonged operation, detrimentally impacting the fluorescent attributes of lead-free DPs. To address this challenge, in situ synthesis of lead-free DP nanocrystals (NCs) within KIT-6 mesoporous molecular sieves is proposed, yielding Cs2AgIn0.98Bi0.02Cl6@KIT-6 NCs with enhanced optical qualities. Experimental results demonstrate a marked enhancement in the fluorescence thermal stability of these NCs, attributed to the protective KIT-6 shell layer. Subjected to high power operation (100 mA) for 270 minutes, the fabricated orange light-emitting diode (LED) device maintained 80% of initial luminous efficiency, despite the resultant elevated surface temperature of 326.8 K. Therefore, this novel in situ assembly approach significantly bolsters the operational stability of lead-free DPs, paving the way for their potential commercial applications. © 2024 The Royal Society of Chemistry.Affiliations:(1) Electronic Materials Research Laboratory, Key Laboratory of the Ministry of Education, International Center for Dielectric Research, Shannxi Engineering Research Center of Advanced Energy Materials and Devices, Xi’an Jiaotong University, Xi’an; 710049, China; (2) Frontier Institute of Science and Technology (FIST), Micro- and Nano-technology Research Center, State Key Laboratory for Manufacturing Systems Engineering, Xi’an Jiaotong University, Xi’an; 710049, China; (3) Xi’an Institute of Optics and Precision Mechanics, Shaanxi, Xi’an; 710119, China; (4) Belarusian State University of Informatics and Radioelectronics, P.
