Abstract The CsPbX3 (X=Cl, Br) microcrystals are obtained in a PbX2 (X=Cl, Br) matrix doped with Cs ions (C Cs=0.1–1 mol %). Spectral and kinetic parameters of the intrinsic luminescence of the CsPbX3 single crystals are presented. For the CsPbCl3 microcrystals, a quantum-confinement effect is detected, which reveals itself as a decrease in the lifetime of the free exciton luminescence. A mechanism of formation of a CsPbX3 microcrystal in a PbX2 matrix is proposed.
