The luminescence and scintillation properties of Tl- and Ce-doped Cs2HfCl6 crystals were investigated by photoluminescence and radioluminescence spectroscopy. In the photoluminescence spectra, emission bands of the activators were observed at 500 nm for Tl-doped Cs2HfCl6, and at 340 and 380 nm for Ce-doped Cs2HfCl6. The radioluminescence bands were observed at 405 and 430 nm for Tl- and Ce-doped Cs2HfCl6, respectively. Scintillation decay time constants for the Tl- and Ce-doped Cs2HfCl6 were smaller than those for the corresponding undoped crystals. Scintillation light yields for Tl- and Ce-doped Cs2HfCl6 were estimated to be 23,700 and 15,700 photons/MeV, respectively.
