This work focuses on the qualitative study of the preparation and optical characterization of CsPbBr3 perovskite nanorods. The first part contains a brief description of 3D, 2D and 0D perovskite nanostructures, and then focuses on the description of the 1D structure - perovskite nanorods, their possible crystal structures, stability, possible preparation methods, optical properties and use in various optoelectronic devices. The practical part discusses in detail the preparation of CsPbBr3 perovskite nanorods using colloidal synthesis based on ligand-assisted reprecipitation and chemical division at room temperature. Furthermore, the synthesized nanorods are analyzed for morphology and their absorption and photoluminescence spectra are measured with the aim of verifying the dependence of optical properties on the mentioned morphology.
