Abstract

In recent years, the field of metal-halide perovskite emitters has rapidly emerged as a new community in solid-state lighting. Their exceptional optoelectronic properties have contributed to the rapid rise in external quantum efficiencies (EQEs) in perovskite light-emitting diodes (PeLEDs) from <1% (in 2014) to over 30% (in 2023) across a wide range of wavelengths. However, several challenges still hinder their commercialization, including the relatively low EQEs of blue/white devices, limited EQEs in large-area devices, poor device stability, as well as the toxicity of the easily accessible lead components and the solvents used in the synthesis and processing of PeLEDs. This roadmap addresses the current and future challenges in PeLEDs across fundamental and applied research areas, by sharing the community’s perspectives. This work will provide the field with practical guidelines to advance PeLED development and facilitate more rapid commercialization.

过氧化物发光二极管路线图
近年来,金属卤化物包晶发光体领域迅速崛起,成为固态照明领域的一个新群体。由于其卓越的光电特性,包晶发光二极管(PeLEDs)的外部量子效率(EQEs)从 2014 年的小于 1% 迅速上升到 2023 年的 30%。然而,PeLED 的商业化仍面临一些挑战,包括蓝/白光器件的 EQE 相对较低、大面积器件的 EQE 有限、器件稳定性差,以及在合成和加工 PeLED 时使用的易获取铅成分和溶剂的毒性。本路线图通过分享社区的观点,解决了当前和未来 PeLED 在基础和应用研究领域所面临的挑战。这项工作将为该领域提供切实可行的指导方针,以推动 PeLED 的发展并促进更快的商业化。
