description: The aim of the work was to develop a technique for the synthesis of halide perovskite nanoparticles CsPbBr3 and study their properties. Along with CsPbBr3 particles, samples of the composition CsPbBr3/Cs4PbBr6 were synthesized. The paper considers the properties of halide perovskite nanocrystals and factors affecting their luminescent characteristics, as well as a comparative analysis of various methods for the synthesis of CsPbBr3 nanoparticles. During the experiments, a series of samples of CsPbBr3 and CsPbBr3/Cs4PbBr6 were synthesized by the method at room temperature with a different ratio of nonpolar solvent (toluene). The effect of the nonpolar solvent ratio on the physicochemical properties of the obtained perovskite nanoparticles has been studied. The phase composition and crystal structure of the samples were analyzed using X-ray phase analysis. The surface morphology and sizes of nanoparticles were studied by scanning electron and transmission electron microscopy. Luminescent characteristics (luminescence spectra and quantum yield) were studied using absolute quantum yield luminescence spectrometry. The conducted research is both fundamental and applied. The obtained data expand the already existing ideas about perovskite halide structures, which are promising materials for use in applied optics, optoelectronics, photonics, and medicine.
