摘要

聚氯乙烯吡咯烷酮（PVP）作为中间层被引入，以阻止过多的电子注入到基于inp的QDs层中，同时减少泄漏电流。优化后的器件实现了23.5%的峰值外量子效率（EQE）和超过800小时的T95工作寿命，初始亮度为1,000 cd m−2，发光波长为624 nm。更多细节可以在陈飞、沈怀滨、唐爱伟及其同事的文章2402677中找到。

Efficient and Long Lifetime Red InP-Based QLEDs Enabled by Simultaneously Improved Carrier Injection Balance and Depressed Leakage (Advanced Optical Materials 12/2025)

Light-Emitting Diodes

Polyvinyl pyrrolidone (PVP) is introduced as an intermediate layer to block excessive electron injection into the InP-based QDs layer while simultaneously reducing leakage current. The optimized device achieves a peak external quantum efficiency (EQE) of 23.5% and a long T₉₅ operational lifetime of over 800 hours at an initial luminance of 1,000 cd m⁻² for red InP-based QLEDs emitting at 624 nm. More details can be found in article 2402677 by Fei Chen, Huaibin Shen, Aiwei Tang, and co-workers.
