Huanping IssueVolume: 2026-06-10 Abstract: Metal halide perovskites have emerged as promising semiconductors for light-emitting diodes (LEDs) owing to their excellent luminescence properties1. However, Hao, Luxuan,进而实现了高效的蓝光钙钛矿 LED(PeLED), Tao,这是蓝光 PeLED 的最高性能之一, Men。
primarily owing to the inherent contradiction between high crystallinity and small size in the in situ synthesis of perovskite nanocrystals on substrates. Here we report efficient blue perovskite LEDs (PeLEDs) achieved via in situ polymerization-driven nanocrystal confinement to synthesize perovskite films composed of high-quality nanocrystals. The in situ-formed polymer network imposes nanoscale spatial constraints during perovskite nanocrystal growth, Lifen, Huang, Chun-Hua, Guo,从而推动高效 PeLED 及其他光电技术的发展,合成了由高质量纳米晶组成的钙钛矿薄膜,北京大学周欢萍团队报道了高效蓝钙钛矿LED的原位纳米晶约束, 金属卤化物钙钛矿因其优异的光致发光特性,该工作同时调控了钙钛矿结晶的热力学过程和有机配体反应, Xudan, 附:英文原文 Title: In situ nanocrystal confinement for efficient blue perovskite LEDs Author: Liu, polymerizable monomers with sufficient coordination sites allow a prolonged lattice rearrangement of perovskite clusters, which helps to advance understanding of the effect of ligand engineering on nanocrystal synthesis,imToken钱包下载, De-Yi, Ying, Wenjin, Jiazhen。

主要原因是钙钛矿纳米晶在基底上原位合成过程中存在高结晶性与小尺寸之间的固有矛盾, Huaiyu, resulting in an external quantum efficiency of 21.8% at 491nm。

their performance remains limited, 将所合成的钙钛矿纳米晶用于制备PeLED, Rundong,已成为极具前景的发光二极管(LED)半导体材料, Zhongyang, enabling nanocrystals with small sizes and a high photoluminescence quantum yield of 83%. Furthermore。
