Structural phase transitions and photoluminescence mechanism in a layer of 3D hybrid perovskite nanocrystals

AIP Advances, 2020
Although structural phase transitions in single-crystal hybrid methyl-ammonium (MA) lead halide perovskites (MAPbX3, X = Cl, Br, I) as a function of temperature are common phenomena, they have never been observed in the corresponding nanocrystals.
