Submicron CsPbBr3 crystallites prepared through in situ moisture-driven decomposition of Cs4PbBr6 microcrystals

Optical gain in submicron crystals is difficult to sustain because light confinement and radiative recombination are highly sensitive to particle size and local structure. Here we show that restricting the moisture-induced transformation of non-emissive Cs4PbBr6 microcrystals pro...
