The photoluminescence and scintillation properties of Cs2HfCl6 and Csl2ZrCl6 crystals were investigated. Two emibion bands in the photoluminescence spectra were observed at 375 and 435nm for the Cs2HfCl6 crystal and at 440 and 479nm for the Csl2ZrCl6 crystal. Similar spectra were observed for radioluminescence. The decay time constants were found to be about 2.2 and 8.4 μs for Cs2HfCl6 and 1.5 and 7.5 μs for Csl2ZrCl6. The scintillation light yields were estimated to be 27,500 and 25,100 photons/MeV for Cs2HfCl6 and Csl2ZrCl6, respectively.
