金属卤化物钙钛矿具有优异的光电性能, 在太阳能电池、光电探测等领域有着广泛的应用。该材料还具有优越的发光性能, 通过调节卤素原子的种类与比例, 可以实现可见光范围内的全波段发光; 此外, 其半峰全宽很窄, 故在显示等领域也具有广阔的应用前景。这些特点使金属卤化物钙钛矿非常适于作激光增益介质, 加上其低维材料本身就可以作为光学谐振腔, 因此低维金属卤化物钙钛矿实现激光输出成为可能。相关的研究已经取得了重要的进展。

Metal halide perovskites possess excellent photoelectrical properties and have extensive applications in the fields like solar cells and photoelectric detection. They also show wonderful emission properties and full band emission in the visible range can be realized by adjusting the type and ratio of halide atoms. In addition, the full width at half maximum of the emission light is narrow, which makes this kind of materials widely used in the fields like display. These properties make metal halide perovskites very suitable as laser gain materials. Moreover, the low-dimensional metal halide perovskites themselves can be used as a natural optical cavity, which makes lasing possible. Much significant progress has been made on the related research.
