Light-emitting diodes (LEDs) based on halide perovskite nanocrystals have attracted extensive attention due to their considerable luminescence efficiency, wide color gamut, high color purity, and facile material synthesis. Since the first demonstration of LEDs based on MAPbBr nanocrystals was reported in 2014, the community has witnessed a rapid development in their performances. In this review, a historical perspective of the development of LEDs based on halide perovskite nanocrystals is provided and then a comprehensive survey of current strategies for high-efficiency lead-based perovskite nanocrystals LEDs, including synthesis optimization, ion doping/alloying, and shell coating is presented. Then the basic characteristics and emission mechanisms of lead-free perovskite and perovskite-related nanocrystals emitters in environmentally friendly LEDs, from the standpoint of different emission colors are reviewed. Finally, the progress in LED applications is covered and an outlook of the opportunities and challenges for future developments in this field is provided.
基于卤化物钙钛矿纳米晶体的发光二极管（LED）因其显著的发光效率、宽色域、高色纯度以及简便的材料合成方法而备受关注。自2014年首次报道基于MAPbBr纳米晶体的LED以来，该领域的性能得到了迅速发展。在这篇综述中，我们首先回顾了基于卤化物钙钛矿纳米晶体的LED的发展历程，然后全面介绍了当前提高基于铅基钙钛矿纳米晶体LED效率的策略，包括合成优化、离子掺杂/合金化以及壳层包覆。接着，从不同发射颜色的角度出发，综述了环境友好型LED中无铅钙钛矿及钙钛矿相关纳米晶体发光体的基本特性和发射机制。最后，涵盖了LED应用方面的进展，并对该领域未来发展的机遇和挑战进行了展望。
