Description
Summary:Mechanochemical treatment of an equimolar mixture of lead and cesium bromides in the absence of solvent gave inorganic halide perovskite CsPbBr 3 with characteristic orthorhombic structure consisting of individual nanoparticles with diameter 10-50 nm and nanoparticle agglomerates with diameter up to 200 nm. An effect of dimethylformamide on the structural and spectral properties of the prepared perovskite was discovered. X-ray diffraction data indicated that mechanochemical synthesis contributes to nanostructuring of CsPbBr 3 as nanosheets. Nonstationary photoluminescence data indicated that the prepared material has a small amount of defects.
