The luminescent kinetic parameters of the CsPbCl3 nanocrystals dispersed in matrices of solid solutions Rb1-xCsxCl (x=0.05-0.2) were studied under pulse synchrotron radiation excitation. Formation of CsPbCl3 nanocrystals is confirmed by manifestation of the quantum size effect, which is displayed by a short-wave shift of the exciton luminescence maximum and an essential shortening of the luminescence decay time for of CsPbCl3 nanocrystals as compared to that for an excitonic luminescence of a bulk single crystal CsPbCl3. For the first time, using the atomic force microscopy method, the lead-containing nanocrystals embedded in a matrix of the Rb0.95Cs0.05Cl solid solution have been directly observed.
