Perovskite-related Cs4PbBr6 nanocrystals present a "zero-dimensional" crystalline structure where adjacent [PbBr6]4– octahedra do not share any corners. We show in this work that these can be converted into "three-dimensional" CsPbBr3 perovskites by extraction of CsBr. This conversion drastically changes the optoelectronic properties become highly photoluminescent. The CsBr achieved either thermal annealing (physical approach) or chemical reaction with Prussian Blue (chemical approach)....
CsPbBr3 nanocrystals passivated with short molecular ligands and deposited on a substrate were annealed from room temperature to 400 °C in inert atmosphere. Chemical, structural, morphological transformations monitored situ ex by different techniques, while optoelectronic properties of the film also assessed. Annealing at 100 resulted 1 order magnitude increase photocurrent photoresponse as result partial sintering NCs residual solvent evaporation. Beyond 150 original orthorhombic partially...
