We analyzed the luminescence and scintillation properties of CsPbCl3 single crystals. La and Ag were chosen as the dopants, although Ag proved to have little effect on the scintillation properties. In the photoluminescence spectra, in addition to the free exciton band at 425nm, an additional band was observed at 440nm at low temperatures for the La-doped crystals. The scintillation spectrum of the undoped crystal was composed of the free exciton band and a broad band at 600 nm, which is ascribed to lattice defects. The La doping strongly suppressed both the broad band and the slow scintillation component, which is ascribed to the emission at lattice defects.
