Reviewer: Ing. Petr Viewegh, Ph.D.
This bachelor thesis deals with the perovskite CsPbBr3. The thesis presents properties and different ways of preparing nanostructures of this inorganic perovskite. The emphasis is placed on physical vapor deposition using effusion cells. The experiments carried out to prepare nanocrystals and nanowires and the subsequent analysis of their morphology, composition and optical properties are described. The effect of the electron beam and long-term exposure to air on the optical properties is studied. Also, the concept of an experiment that should result in the replacement of lead in the perovskite structure by tin is presented.
Perovskites, CsPbBr3, preparation of low-dimensional nanostructures, nanocrystals, evaporation, photoluminiscence.
