摘要

在光电显示领域中，量子点发光二极管（quantum dots light-emitting diode，QLED）因其宽的光谱可调性、窄的半峰全宽、高的色纯度等优异性能而受到广泛关注，并被认为是下一代显示技术极为突出的候选者。目前，镉基QLED的红、绿、蓝三色发光性能已十分接近有机发光二级管的水平，但是镉元素对人体及环境具有严重的危害性。InP量子点具有较大的激子波尔半径、宽的光谱可调性（可覆盖整个可见光区）以及与镉基量子点相媲美的光电性质，而成为最有望替代镉基量子点的环境友好型量子点。因此，本文详细总结了近年来InP量子点的合成（核壳的结构、配体的选择等）与荧光性能及其QLED发光性能等方面的研究进展，并对InP QLED所面临的问题、挑战及其可行性解决方案进行了讨论和展望。

Abstract

In the field of optoelectronic display

quantum dot (QD) display has attracted intensive attention due to its wide spectral adjustability

narrow full width at half maxima (FWHM)

high color purity and other excellent properties

which is considered to be an outstanding candidate for the next generation of display technology. The performance of quantum dots light-emitting diodes (QLEDs) has been rapidly improved

and especially the red

green and blue cadmium-based QLEDs all show comparable luminescent performance to organic light emitting diodes (OLED). However

cadmium is a seriously hazard to human body and environment and violates sustainable development path. Therefore

researchers pay more attention to environment-friendly quantum dot materials

among which InP quantum dot with the outstanding properties such as large Bohr radius

wide spectral adjustability and so on has become the most promising environment-friendly material to replace cadmium-based quantum dots. In this work

the recent progress about the synthesis and photoluminescence performance of InP quantum dots (core-shell structure

ligand selection

etc.

) and the luminescent performance of InP QLED are summarized

and the current problems and challenges as well as the feasible solutions in InP QLED are discussed and outlooked.
