Composition tunable and stable spontaneous emission and lasing in Cd-alloyed perovskite microdisks†
Abstract
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 CsPb1−xCdxBr3 compositions, propose pathways of photoexcited charge carrier dynamics in them, and show improved stability of lasing in whispering gallery mode microdisks.
