摘要：

Polarization of the free exciton luminescence of CsPbBr3-type semiconducting nanocrystals of perovskite structure dispersed in CsBr:Pb crystal has been observed for the first time. The polarization spectra, temperature and angular dependences of the degree of polarization as well as the dependence of polarization characteristics on size and shape of CsPbBr3 nanocrystals have been studied. The conclusions have been made about the orientation of anisotropic CsPbBr3 nanocrystals with respect to CsBr crystal axes, the origin of optical transitions responsible for the exciton emission as well as about the mechanism of the production of the nanocrystals in the process of thermally stimulated diffusion of Pb2+ ions in CsBr:Pb crystal lattice.
