The recombination mechanisms leading to amplified spontaneous emission at thetrue-green wavelength in CH3NH3PbBr3perovskites

We investigated the mechanisms of radiative recombination in aCH3NH3PbBr3hybridperovskitematerialusing low-temperature, power-dependent (77 K), and temperature-dependentphotoluminescence(PL)measurements. Twobound-excitonic radiative transitions related to grain size inhomogeneity were identified.Bot...
