Design of functional layers for long-lifetime quantum dot light-emitting diodes
量子点发光二极管(Quantum Dot Light-emitting Diode,QLED)具有卓越的性能,如高色纯度、宽色域和可调节的发射波长.这些独特的优点使其成为下一代显示器和固态照明领域的有力竞争者.本文系统地分析了长寿命QLED器件的设计策略,从量子点发光层(Emitting Layer,EML)、电子传输层(Electron Transport Layer,ETL)、空穴传输层(Hole Transport Layer,HTL)等3个核心功能层梳理长寿命QLED器件的共性特征和规律,为后续蓝光QLED器件和更多量子点体系QLED器件寿命的提升提供有益的思路,对长寿命QLED技术的发展提出展望.
Quantum dot light-emitting diodes(QLEDs)exhibit outstanding properties,such as high color purity,wide color gamut,and tunable emission wavelengths.These advantages make them strong competitors in the fields of next-generation displays and solid-state lighting.There are three core functional layers in QLED:the quantum dot Emitting Layer(EML),Electron Transport Layer(ETL),and Hole Transport Layer(HTL),which are of great significance for the lifetime of QLEDs.In this review,we summarize the common characteristics and patterns of long-lifetime QLED devices from researches about these three functional layers.We systematically analyze the design strategies for long-lifetime QLED devices.This paper provides valuable insights for subsequent lifetime research on blue QLED devices and QLED devices based on more quantum dot systems,and presents an outlook on the development of long-lifetime QLED technology.
