Organolead Halide

Low threshold random lasing was observed in a millimeter-sized 2D single-crystalline perovskite microrod. The lower value of the threshold can be attributed to the strong light confinement, long mean free path and large exciton binding energy.

Quasi-2D metal halide perovskites are promising candidates for light-emitting application owing to their large exciton binding energy and strong quantum confinement effect. Usually, quasi-2D perovskites are composed of multiple phases...
