摘要

全无机铅镉混合阳离子卤化物包晶石已成为具有更好光学和光电特性的半导体。我们在块状 CsPb1-xCdxBr3 成分中建立了光致发光与镉含量 x 之间的可靠相关性，提出了其中光激发电荷载流子动力学的途径，并展示了在耳语画廊模式微晶盘中更高的激光稳定性。

Composition tunable and stable spontaneous emission and lasing in Cd-alloyed perovskite microdisks†

All-inorganic Pb–Cd mixed-cation halide perovskites have emerged as semiconductors exhibiting improved optical and optoelectronic properties. We establish a reliable correlation between photoluminescence and Cd content x in bulk CsPb_1−xCd_xBr₃ compositions, propose pathways of photoexcited charge carrier dynamics in them, and show improved stability of lasing in whispering gallery mode microdisks.
