Abstract :

Inorganic metal halide perovskite quantum dots (PQDs) have recently emerged as promising candidates for color conversion materials in Micro-LED displays, due to their outstanding color purity, high absorption coefficient, tunable emission wavelength. However the inferior stability and undesirable photoluminescence quantum yield (PLQY) restrict their particle applications. Herein, CsPbX3/PMMA (X = Br, I) composites with improved stability and optical performance were successfully prepared by a general and mild in-situ polymerization strategy. The ester carbonyl (C--O) group in MMA formed complexes with Pb2+, leading to the in-situ thermal polymerization of polymethyl methacrylate (PMMA) under the action of the initiator. The multifunctional PMMA can efficiently passivate halogen vacancies while acting as a barrier against the degradation caused by heat, water, and oxygen. As a result, the PLQYs and stability of PMMA-coated CsPbX3 PQDs have been significantly improved. When implementing CsPbX3/PMMA/PDMS composites as color conversion layers in Micro-LEDs, they achieve an impressive color gamut of 127.23% with excellent stability. We believe our work will stimulate the exploration of perovskite/polymer composites for industrial Micro-LED applications.

Abstract :

When quantum dot diffusion plates (QDDPs) are used as phosphor conversion materials for high-power lighting, transparent ceramics (TCs) can be used to prevent thermal damage of QDDPs. The spectral, suitable for diverse lighting environments, can be precisely calibrated by modifying their ratio. The temperature dependent photoluminescence spectra, fluorescence lifetime, Huang Rhys factor and activation energy of TCs were studied in detail. It was evident from the results that the intensity of TCs remained above 89% even at 423 K, while fluorescence lifetime remained stable, nearly 64 ns. Huang-Rhys factor and activation energy were consistently measured at 1.81 and 0.13 eV, respectively. The extraordinary luminescent stability of TCs revealed their integral role in providing reliable protection for QDDPs. The spectra of LEDs/LDs were successfully predicted using Monte Carlo ray tracing method. The service condition under high-energy laser was studied using finite element method. White light with Commission Internationale de l'Eclairage (CIE) of (0.38, 0.39) and (0.31, 0.34) and luminous efficiency of 58 and 150 lm/W were prepared by combining QDDPs/TCs with LEDs/LDs, and the Color Rendering Index (CRI) reached a remarkable 88.4 and 78.8. A detailed exploration of the proficient thermal management was accomplished using finite element analysis, with the simulated outcomes matching closely with the experimental results. © 2024 Elsevier Ltd and Techna Group S.r.l.

Abstract :

Quantum dots(QDs)are widely used in luminescence and display,solar cells,photocatalysis and other fields due to their excellent photovoltaic properties,and its discovery and synthesis won the 2023 Nobel Prize in Chemistry. Micro-LED full-color display technology using quantum dot color conversion does not require mass transfer technology and is expected to achieve large-scale mass production. However,there are still limitations to the performance and lifespan of quantum dots under intense Micro-LED light excitation. Based on,this paper studies the Micro-LED color conversion technology and its characteristics based on quantum dot@ordered mesoporous(QDs@SBA-15)composite materials. The unique pore structure of the ordered mesoporous materials not only can effectively improve the Micro-LED color conversion and light extraction efficiency,but also the dense ordered mesoporous material guarantees the stability of the quantum dots to a certain extent. Firstly,we established a Micro-LED simulation model through the Finite-difference time-domain(FDTD)method to investigate the effects of the particle size of the quantum dots and the pore size of the ordered mesoporous materials on the light extraction efficiency. Based on the guidance of simulation results,QDs@SBA-15 composites were further prepared by physical blending method,characterized by transmission spectroscopy,fluorescence excitation spectroscopy and UV-Vis absorption spectroscopy,and the concentration ratios were determined. Finally,we combined this composite material with polydimethylsiloxane (PDMS)to solidify it into a film and studied its photoluminescence performance. The experimental results showed that the matching degree of the quantum dot particle size and the pore diameter of the mesoporous material,as well as the concentration ratio of quantum dots and ordered mesoporous materials,is crucial to the luminous efficiency of QDs@SBA-15 composite materials and the color conversion performance of Micro-LED. Through the optimization,the resulting composites can obtain excellent luminescence performance and good environmental stability,compared with the pure quantum dots color conversion layer,the light extraction efficiency of the composite material has been improved by 81. 73%,and the environmental stability of the composite material has been improved by 14. 33%. The color gamut of tri-color devices obtained with Micro-LED as the blue light source reached 104. 52% NTSC. This research provides theoretical guidance for quantum dot color conversion Micro-LED display technology,and opens up a new path to realize the full-color Micro-LED. © 2024 Chines Academy of Sciences.

Abstract :

光波导组合器在增强现实显示的出瞳扩展和外观薄化方面颇具优势。出瞳扩展技术是通过在耦出区域诱导多次衍射,将光线引导至人眼。然而,这种多次衍射可能导致出瞳亮度在沿光路径的空间分布上逐渐减弱,从而造成亮度不均。特别是当使用液晶制备而成的偏振体全息光栅作为耦合元件时,由于光栅仅对一种圆偏振光敏感,与之正交的圆偏振光会被直接透射,导致波导系统的能量利用率并不高。针对这一挑战,本文提出了一种实现左旋和右旋圆偏振光复用的偏振体全息光栅光波导AR显示光学系统,同时实现了大出瞳尺寸和良好入眼均匀性。在理论设计和仿真方面,首先通过k空间理论设计了大视场角下的光栅结构,再以微型发光二极管(Micro-LED,μLED)作为微显示屏,设计了一套与之匹配的投影镜头,并对整个波导系统进行了成像仿真。在实验部分,制备了中心波长为532 nm、出瞳尺寸为45 mm×25 mm的偏振体全息光栅波导。实验结果显示,该波导系统在基板折射率为1.51下的对角线视场角达到了预期的32.86°。相比于仅响应单一圆偏振光的方案,采用九点法测得的均匀性提升了48.8%,整体均匀性提升了34.1%,波导组合器的光学效率也实现了1.2倍的提升。本文工作为偏振体全息光栅波导的设计提供了宝贵的指导和参考。

Abstract :

Mini-LED, with its small size, flexibility, and stability, can be applied in various fields. It is necessary to adopt different driving methods in different scenarios. In this work, a new type of Mini-LED driving technique called non-contact alternating current power transmission (NCACPT) driving based on magnetic coupling resonant are designed, which uses the alternating current (AC) from the receiving coil to drive Mini-LED. This new device could be called NCACPT-LED. Novel equivalent circuit models are proposed and have been employed to conduct finite element simulation on Mini-LED under this driving technique. Based on the results obtained from the finite element simulation, the sudden extinction phenomenon and the resonant frequency shift are explained. Electrical and optical characteristics of NCACPT-LED are investigated. The novel LED device proposed in this study, coupled with the analysis of the experimental phenomena, contributes to the progress of Mini-LED applications across various domains.

Single-layer waveguide with compound metasurfaces for highly efficient and chromatic-aberration-free augmented reality near-eye displays SCIE

Abstract :

Augmented reality (AR) near-eye displays seamlessly integrate virtual information with real world, in which the optical waveguide is the key component functioned as a coupler. Due to strong chromatic aberration, independent waveguides are always indispensable to separate the three primary colors that inevitably brings larger and thicker appearance. To address this, this paper proposes a new chromatic-aberration-free single-layer waveguide for AR displays by integrating a double-layer grating metasurface (MS) and the covered cylindrical MSs. The double-layer grating MS breaks through the limitations on a narrow wavelength band, enabling high diffraction efficiency for incident light deflection across the entire visible spectrum. Further, the cylindrical MSs provide accurate control over incident angles, not only overcoming the challenge of total reflection but also effectively eliminating chromatic aberration. Design results show that the proposed structure achieves an impressive diffraction efficiency of over 80 % for blue and green light and over 90 % for red light with an outstanding diffraction angular difference lower than 2.5 deg. Real-time ray tracing simulation demonstrates the capability of the designed AR engine to achieve high-resolution full-color imaging. The compound MSs enable precise light and color control for a single-layer waveguide coupler with exceptional diffraction efficiency and minimal chromatic aberration, which show great potential for cutting-edge AR applications.

Enhancement of photo-oxidation resistance of quantum dots by hindered phenol and its application in diffusion plate SCIE

Abstract&Keyword Cite

Abstract :

Alloyed quantum dots (QDs) show great potential for photoluminescence (PL) applications. However, the oxidative decay of QDs during photoexcitation has been a major hurdle to the application of QDs. Blocking water-oxygen erosion by coating oxides on the surface of QDs is a common technique. Even though, this approach often leads to alterations in the optical properties of QDs and reduced compatibility with polymers. In this paper, hindered phenol was utilized to treat QDs to form QD/Hindered phenol complexes. Using the reduction of phenolic hydroxyl group in the hindered phenol, the hindered phenol was used as an exhausted substance to protect QDs from oxidation. After 450 h of aging, the obtained QD/Hindered phenol complex kept the photoluminescence quantum yield (PLQY) at 48 %. The luminance of the QD diffusion plate prepared by the QD/Hindered phenol complexes maintained above 98 % of the initial value after aging 1032 h. The introduction of phosphite ester further improved the photostability of QD/Hindered phenol complex under blue-light excitation. This technique promotes the application of QDs in polymers and offers a new reference for improving the stability of QDs under photoexcitation.

Abstract :

Over the past few years, light-emitting diodes (LEDs) have emerged as an efficient replacement for standard incandescent and fluorescent lamps, due to their superior efficiency, energy conservation, service longevity, reliability, and affordability. However, identifying a red emitter for white LEDs has presented significant challenges. This study seeks to synthesize and analyze a novel red emitter, investigating its potential use in white LEDs and indoor plant growth lighting. The Sr2Lu(Nb,Mn)O6 is manufactured employing the traditional high-temperature solid-phase method. The internal and external quantum efficiencies (IQE and EQE) of double perovskites reached 32.39% and 21.67%. The g value calculates to 2.146, which corroborates that the magnetic dipolar transitions of Mn4+ ions inhabit symmetric octahedral sites. First-principles investigations are utilized to unveil local electronic structures. Emission spectra reveal a substantial broad red emission peak at 688 nm. The Tanabe-Sugano diagram is applied to understand the luminescence mechanism. Additionally, the evaluation of parameters such as the internal UV emission ratio, crystal field strength, and Racah parameters is conducted. The luminescent intensity of the Sr2Lu(Nb,Mn)O6 can still be maintained at 60% upon reaching a temperature of 423 K. The findings suggest that Sr2Lu(Nb,Mn)O6 offers a novel alternative for white LEDs and indoor plant growth lighting. This paper unveils the local electronic structure of manganese-doped Sr2LuNbO6 double perovskite red emitter, and elaborates on its crystal structures, luminescence properties, crystal field properties, thermal stability, and energy transfer mechanisms. Based upon first principles calculations, reveals the superior photoelectric performance of it, positioning it as a potential solution for the red-deficiency in white LED and indoor lighting technologies. image

Abstract :

The potential of organic-inorganic hybrid perovskites, owing to their distinct photoelectric attributes and boosted photoluminescence stability, has garnered substantial attention. Despite comprehensive examinations of the synthesis and optical characteristics of FAPbBr(3) crystals, the understanding of their microstructure's implication on photoelectric applications, their electronic configuration, and electron-phonon interplay remains vague. In this study, we detailed the electronic configuration, phonon dispersion, and vibrational properties using density functional theory. We further calculated the formation enthalpy stability diagram. Characterization and calculation of the crystalline structure were accomplished via Rietveld refinement. Phonon dispersion curves, as well as total and partial phonon densities of states, were also calculated. The theoretical results align well with experimental Fourier infrared and Raman spectra. Beyond elementary characterization, we explored the photoelectric qualities of FAPbBr(3) crystals, thereby reaffirming the outstanding photoelectric attributes and extensive application potential. A non-contact fixed-point lighting device was designed based on the principle of electromagnetic induction coils, which proved the uniformity of crystal luminescence. According to the first principle, FAPbBr(3) possesses a Poisson ratio of 0.32, indicative of high flexibility, emphasizing their superb photoelectric characteristics and vast application scope.
