Abstract

Halide perovskites have emerged as superstar materials for optoelectronic devices. Besides the fever of research in solar cells, these materials show great promise on light emitting diodes (LEDs), photodetectors and lasers as well. Rapid advances in bulk perovskite materials aroused universal interest for the development of perovskite nanocrystals, inspired by the great progress of classic colloidal semiconductor quantum dots. Perovskite nanocrystals have been synthesized based on solution process and exhibited high luminescence quantum yield, sharp emission peak, and emission color tunability. Significant progresses have been made about the application of perovskite nanocrystals for LED and lasers in recent years. In this paper, we will comprehensively introduce the synthesis strategies, physical and chemical characteristics, as well as their applications in optoelectronic devices.

摘要

卤化物钙钛矿已成为光电器件的超级明星材料。除了太阳能电池的研究热潮外，这些材料在发光二极管（LED）、光电探测器和激光器方面也显示出巨大的潜力。受经典胶体半导体量子点的巨大进展启发，体相钙钛矿材料的快速发展引起了人们对钙钛矿纳米晶体开发的广泛关注。钙钛矿纳米晶体已通过溶液法合成，并表现出高发光量子产率、尖锐的发射峰和发射颜色可调性。近年来，钙钛矿纳米晶体在LED和激光器应用方面取得了重大进展。在本文中，我们将全面介绍其合成策略、物理和化学特性，以及它们在光电器件中的应用。
