Metal halide perovskites, known for their pure and tunable light emission, near-unity photoluminescence quantum yields, favorable charge transport properties, and excellent solution processability, have emerged as promising materials for large-area, high-performance light-emitting diodes (LEDs). Over the past decade, significant advancements have been made in enhancing the efficiency, response speed, and operational stability of perovskite LEDs. These promising developments pave the way for a broad spectrum of applications extending beyond traditional solid-state lighting and displays to include visible light communication (VLC) and lasing applications. This perspective evaluates the current state of perovskite LEDs in those emerging areas, addresses the primary challenges currently impeding the development of perovskite-based VLC systems and laser diodes, and provides an optimistic outlook on the future realization of perovskite-based VLC and electrically pumped perovskite lasers.
金属卤化物钙钛矿以其纯净且可调节的发光、近乎单位的光致发光量子产率、良好的电荷传输特性以及出色的溶液可加工性而闻名，已成为用于大面积、高性能发光二极管（LED）的有前途的材料。在过去十年中，在提高钙钛矿LED的效率、响应速度和工作稳定性方面取得了重大进展。这些有前景的发展为广泛的应用铺平了道路，其范围超越了传统的固态照明和显示器，还包括可见光通信（VLC）和激光应用。本观点评估了钙钛矿LED在这些新兴领域的当前状态，解决了目前阻碍基于钙钛矿的VLC系统和激光二极管发展的主要挑战，并对基于钙钛矿的VLC和电泵浦钙钛矿激光器的未来实现提供了乐观的展望。
