Abstract ：
The light source of traditional edge-lit backlight modules typically consists of LED bars which composed of multiple LED chips. However, the spacing between the chips can create distinct bright and dark spots (Hot Spot) on the input surface of the light guide plate (LGP), thereby affecting the optical performance of the backlight module. In this paper, we proposed an edge-lit backlight module with staggered light bars, incorporating a light propagation cavity design to enhance light receiving efficiency and eliminate Hot Spot. Firstly, we designed the structure of the staggered light bars and the light propagation cavity. Secondly, the advantages of the new backlight module design in eliminating Hot Spot were verified through TracePro simulations. The simulation results showed that the maximum irradiance of the backlight module reached 81,010 W/m(2), and the luminance uniformity peaked at 75.142 %. Compared to the traditional backlight modules, the light receiving efficiency was increased by 6.62 %, and the luminance uniformity was improved by 1.34 times, which effectively mitigated the Hot Spot. Finally, we discussed the impact of the improved backlight module in reducing the thickness of the LGP and decreasing the number of LED chips, achieved superior optical performance. This study demonstrates the significant advantages of the light propagation cavity in eliminating Hot Spot within backlight modules.

Abstract ：
Quantum dots(QDs)exhibit excellent optical properties with their size tunability,excellent photoluminescence quantum yield(PLQY),and broad spectral absorption,making them an ideal material choice for full-col- or,wide-gamut LED color conversion layers. In particular,MAPbBr3 quantum dots(PQDs)are not only easy to prepare,but also possess excellent photovoltaic properties,and thus are considered to be a material with great potential for commercialization. However,the ligands on the surface of MAPbBr3 PQDs are highly susceptible to detachment after their synthesis,leading to an increase in the density of surface defect states,which makes them less stable under environmental factors such as water-oxygen and temperature,thus further degrading the PLQY. In this study,we propose an efficient one-step strategy for the synthesis of MAPbBr3 PQDs∶MAPbBr3 PQDs with excellent stability and high PLQY,which were successfully synthesized by ligand-assisted redeposition and the innovative use of 2-hex-yldecanoic acid(DA)ligand to replace the conventional oleic acid(OA)ligand at room temperature,and the double-short-chain DA ligand was able to establish a stronger coordination bond with the MAPbBr3 PQDs compared with that of the single-length carbon chain OA ligand. The strong interactions between the ligands and the PQDs contribute to the overall passivation of the lattice defects,thus mitigating the non-radiative recombination process and enhancing the environmental stability. As a result,the modified MAPbBr3 PQDs not only exhibited up to 87. 8% PLQY,but also showed higher stability in both water and oxygen environments. The PL peak of MAPbBr3 PQDs modified with DA ligands remained at 68. 3% of its original value after being left for half a month in a room temperature environment, whereas OA ligand-modified PQDs exhibited almost complete fluorescence burst. Subsequently,the DA ligand-modified green MAPbBr3 PQDs,red CsPbBrI2 PQDs,and blue CsPbCl1. 5Br1. 5 PQDs were coated and cured in a polystyrene(PS)environment to form a film,which can be used as a color conversion material instead of the traditional phosphors for the backlight of light-emitting diode(LED)displays. The color gamut is 137. 09% under NTSC standard. © 2025 Editorial Office of Chinese Optics. All rights reserved.

Abstract ：
Optoelectronic memristors have garnered significant attention for their critical applications in neuromorphic computing. The incorporation of materials with excellent absorption efficiency in the fabrication of photoelectric memristors can significantly enhance the image recognition capabilities. CdS nanorods (NRs) are semiconductors with strong UV light absorption that can effectively improve charge transport characteristics, reduce the loss caused by recombination at the crystal surface, and enhance the light absorption characteristics. In this work, an efficient hot injection method for controlling the growth of CdS NRs or nanosquares (NSs) by optimizing the proportion of dodecanethiol (DDT) is reported. Meanwhile, two-terminal optoelectronic memristors based on CdS NSs and CdS NRs are fabricated in which the conductance of the devices can be continuously modulated under electrical and optical stimulations of different widths/spacings/amplitudes. These advantages impart the device with exceptional electrical and optical synaptic functions including excitability, inhibition, paired-pulse facilitation, short-term/long-term plasticity, and memory-forgetting behavior. In addition, the enhancement of the image recognition efficiency of the device by CdS NRs is demonstrated in experiments with the recognition of the optical image "F". This work offers valuable insights for material selection in the development of future neuromorphic devices.

Abstract ：
Optimizing the three-primary-color perovskite quantum dots (TPC PQDs) is crucial for achieving ultra-wide color gamut displays. Although encapsulation is an effective strategy to improve the stability and optical performance of the TPC PQDs, the chemicals or environment employed in the coating procedure may attack the CsPbX3 PQDs and generate defects, damage, and ligand loss. Herein, a mild, facile and universal hexamethylcyclotrisiloxane (D3) in situ ring opening polymerization strategy is successfully developed for efficiently synthesizing high-brightness and extremely stable TPC CsPbX3@PDMS (X = Cl, Br, I) nanospheres, with particularly friendlyness for fragile red and blue. The formation of Pb & horbar;O bond between polydimethylsiloxane (PDMS) and CsPbX3 passivates the lattice defects, resulting in photoluminescence quantum yields (PLQYs) improvement of approximate to 1.5 times for green and red, astonishingly 2 times for blue PQDs. Also, PDMS shell effectively blocks threats from the environment. Finally, the synthesized CsPbX3@PDMS nanospheres are successfully applied in fabrication of the TPC light emitting diodes (LEDs) and full-color liquid crystal displays (LCDs), achieving impressive ultra-wide color gamuts of 132% and 118% National Television Standards Committee (NTSC), respectively. These findings support the new strategy for synthesizing emerging full-color perovskite nanomaterials and shows great potentieal for high color-rendering displays.

Abstract ：
Multifunctional materials have attracted tremendous attention in intelligent and interactive devices. However, achieving multi-dimensional sensing capabilities with the same perovskite quantum dot (PQD) material is still in its infancy, with some considering it currently challenging and even unattainable. Drawing inspiration from neurons, a novel multifunctional CsPbBr3/PDMS nanosphere is devised to sense humidity, temperature, and pressure simultaneously with unique interactive responses. The carefully engineered polydimethylsiloxane (PDMS) shell enables the reversible activity of the core CsPbBr3, serving a dual role similar to dendrites in conveying and evaluating external stimuli with high sensitivity. Molecular dynamics analysis reveals that the PDMS shell with proper pore density enhances the conductivity in water and heat, imparting CsPbBr3 with sensitive but reversible properties. By tailoring the crosslinking density of the PDMS shell, nanospheres can surprisingly show customized sensitivity and reversible responses to different level of stimuli, achieving over 95% accuracy in multi-dimensional and wide-range sensing. The regular pressure-sensitive property, discovered for the first time, is attributed to the regular morphology of the nanosphere, the inherent low rigidity of the PDMS shell, and the uniform distribution of the CsPbBr3 core material in combination. This study breaks away from conventional design paradigms of perovskite core-shell materials by customizing the cross-linked density of the shell material. The reversible response mechanism of nanospheres with gradient shell density is deeply explored in response to environmental stimuli, which offers fresh insights into multi-dimensional sensing and interactive display applications.

Abstract ：
量子点(Quantum dots)凭借其尺寸可调控、卓越的光致发光量子产率(PLQY)以及宽光谱吸收等特性,展现出了卓越的光学性能,使其成为全彩广色域显示中LED色转换层的理想材料选择.特别是MAPbBr3钙钛矿量子点(PQDs),不仅制备工艺简单,并且还拥有优异的光电性能,因而被视为极具商业化潜力的材料.然而,MAPbBr3 PQDs在合成后其表面的配体极易脱落,导致表面缺陷态密度增加,这使得它们在水氧等环境因素下稳定性较差,最终导致其PLQY进一步降低.本研究提出了一种高效的一步合成MAPbBr3 PQDs策略:通过配体辅助再沉积技术(LARP),并创新性地使用2-己基癸酸(DA)配体替换传统的油酸(OA)配体,在室温条件下成功地合成了具有出色稳定性和高PLQY的MAPbBr3 PQDs.与单长碳链的OA配体相比,双短链的DA配体能与MAPbBr3 PQDs建立起更强的配位键.配体与PQDs之间的强相互作用有助于全面钝化晶格缺陷,从而减弱非辐射过程并提高材料的环境稳定性.因此,DA修饰后的MAPbBr3 PQDs不仅展现出高达 87.8%的PLQY,而且在水氧环境中也表现出更高的稳定性.室温环境下,使用DA配体修饰后的MAPbBr3 PQDs的PL峰值在放置半个月后仍保持在原来的68.3%,而OA配体修饰的PQDs表现出几乎完全的荧光猝灭.随后,将DA配体修饰后的绿色发射MAPbBr3 PQDs、红色发射CsPbBrI2 PQDs以及蓝色发射CsPbCl1.5Br1.5 PQDs置于聚苯乙烯(PS)环境中包覆固化成膜,替代传统荧光粉应用于显示器件发光二极管(LED)的色转换层,测试其色域范围达到了NTSC标准的137.09%.

全无机钙钛矿量子点因其高光致发光量子产率(Photoluminescence Quantum Yield,PLQY)、带隙可调、高色纯度等特性,在宽色域显示上的应用十分广泛,但其表面缺陷与晶格不稳定限制了其进一步应用.通过热注入法将ZnI2作为掺杂剂成功合成了 Zn2+掺杂的CsPbI3量子点(Zn:CsPbI3量子点).试验表明,Zn部分取代了 Pb,钙钛矿晶格逐渐收缩但晶型保持不变,提高了辐射衰减率,有效消除量子点缺陷态.Zn:CsPbI3量子点相较于原始CsPbI3量子点具有更好的相稳定性,PLQY也从56％提升至98％,同时PLQY在10天后仍可保持在80％以上.选用窄发射的Zn:CsPbI3,CsPbBr3与CsPbCl3量子点作为LED颜色转换材料,在国家电视标准委员会(National Television Standards Committee,NTSC)标准下,其色域达到了135.22％,证明了其在直视型LED显示屏或者液晶显示器(Liquid Crystal Display,LCD)背光领域具有潜在应用前景.
