文摘

Luminescence spectral and kinetic characteristics have been studied under the synchrotron excitation in the energy range of 4–20eV for CsPbCl₃ microcrystals dispersed in a PbCl₂ crystal matrix. In the luminescence decay kinetics of the CsPbCl₃ microcrystals, different components have been recorded and connected with the direct excitation of the microcrystals and reabsorption of the self-trapped exciton emission of a PbCl₂ matrix. The decrease of the luminescence decay time of the CsPbCl₃ microcrystals as compared with that characteristic of a CsPbCl₃ single crystal may be caused by the quantum size effect.
