Abstract

The outstanding properties of wide and flexibly tunable emission range, high color saturation, and cost-effectiveness make quantum dots (QDs) promising candidates in display field. However, the vast majority of QDs used in high-performance display devices contain toxic elements such as cadmium (Cd) or lead (Pb). In recent years, with increasing attention to physical health and ecological environment, the application of eco-friendly QDs in light-emitting diodes (LEDs) has been vigorously explored through tremendous efforts in material engineering and device architecture. The external quantum efficiency (EQE) of red InP-based and blue ZnSe-based quantum dot light-emitting diode (QLED) has exceeded 21.4% and 20.2%, which owns good stability and high color purity. In this review, the recent research progress of three major projects implemented on four types of eco-friendly QDs, including existing challenges and possible solutions, and their feedback on device performance are summarized, aiming to provide guidance for the further development of eco-friendly QLEDs.

显示用环保量子点发光二极管的最新进展

量子点具有宽而灵活的可调发射范围、高色彩饱和度和高性价比等特点，是显示领域的理想选择。然而，绝大多数用于高性能显示设备的量子点都含有镉(Cd)或铅(Pb)等有毒元素。近年来，随着人们对身体健康和生态环境的日益关注，通过材料工程和器件架构方面的巨大努力，人们正在大力探索生态友好型量子点在发光二极管(led)中的应用。红色inp基量子点发光二极管(QLED)和蓝色znse基量子点发光二极管(QLED)的外量子效率(EQE)分别超过21.4%和20.2%，具有良好的稳定性和较高的色纯度。本文综述了目前在四种类型的环保qled上实施的三个主要项目的研究进展，包括存在的挑战和可能的解决方案，以及它们对器件性能的反馈，旨在为环保qled的进一步发展提供指导。
