Abstract

Metal halide perovskite materials have demonstrated considerable potential as gain media for laser diodes. However, current research on perovskite lasers predominantly focuses on the visible light region. The development of near‐infrared perovskite lasers with emission wavelengths beyond 850 nm remains a significant challenge. Herein, fully solution‐processed near‐infrared perovskite lasers with tunable emission wavelengths spanning from 872 to 948 nm are presented. By controlling the crystallization time of the FASnI3 perovskite films, near‐infrared lasing at room temperature without external cavities is realized. Through modulating the dimensions of the perovskite films via the incorporation of a large cation PEA+, quasi‐2D perovskites with adjustable lasing wavelengths and enhanced stability are successfully developed. These findings provide a novel approach for the fabrication of near‐infrared lasers, which will facilitate the advancement of lead‐free perovskite lasers.

基于卤化锡钙钛矿的室温近红外激光从三维到准二维

金属卤化物钙钛矿材料作为激光二极管的增益介质已显示出相当大的潜力。然而，目前钙钛矿激光器的研究主要集中在可见光区域。开发发射波长超过850 nm的近红外钙钛矿激光器仍然是一个重大挑战。本文提出了全溶液处理的近红外钙钛矿激光器，其发射波长可调，范围从872到948 nm。通过控制FASnI3钙钛矿薄膜的结晶时间，实现了室温下无外腔的近红外激光。通过加入大阳离子PEA+来调节钙钛矿薄膜的尺寸，成功地开发了具有可调激光波长和增强稳定性的准2D钙钛矿。这些发现为近红外激光器的制造提供了一种新的方法，这将促进无铅钙钛矿激光器的发展。
