摘要

量子点及其发光二极管器件在显示领域展现出极大的潜力。然而，研究较为成熟的镉系量子点和钙钛矿纳米晶由于含有镉和铅等元素，对环境和人类健康有着较大威胁，限制了其更大规模的应用，无镉无铅量子点及其发光二极管器件显示出更大的潜力。目前，红光和绿光的研究进展较快，而蓝光的报道较少，器件性能也明显落后。本文总结了以磷化铟（InP）、硒化锌（ZnSe）和卤化铜基钙钛矿（Cs

）为代表的几种无镉无铅蓝光量子点材料及其发光二极管器件的研究进展，分别从材料的结构设计、制备工艺以及器件的结构优化、性能表征等方面进行了总结和分析，并对未来无镉无铅环保型蓝光量子点及其发光二极管器件的发展进行了展望，从材料和器件两方面分别提出了可以继续探索和发展的方向。

Abstract

Quantum dots and their light-emitting diodes have a great potential in the display industry. However

cadmium-based quantum dots and perovskite nanocrystals

which contain cadmium and lead

posing a great threat to the environment and human health

which limits their large-scale application. Cadmium-free and lead-free quantum dots and their light-emitting diodes show greater potential. At present

there are many researches on red and green emitting

but few reports on blue light emitting. The research progress of several cadmium-free and lead-free environment-friendly blue quantum dots and light-emitting diodes are summarized in this paper

such as indium phosphide (InP)

zinc selenide (ZnSe) and copper halide-based perovskite (Cs

). The structure design

fabrication process of materials and the structure optimization and performance characterization of devices are summarized and analyzed. The future development of cadmium-free and lead-free environment-friendly blue quantum dots and their light-emitting diodes are prospected. The further exploration and development directions are proposed from two aspects of materials and devices.
