Abstract: Luminescence and scintillation properties of Cs 2 HfBr 6 and Cs 2 ZrBr 6 crystals were investigated using photoluminescence (PL) and radioluminescence (RL) spectroscopies. In the PL spectra, emission bands were observed at 435 and 525 nm for Cs 2 HfBr 6 , and at 530 nm for Cs 2 ZrBr 6 . Corresponding emission bands were observed for RL spectra. The scintillation decay time constants of the Cs 2 HfBr 6 and Cs 2 ZrBr 6 crystals were smaller than those of the corresponding Cs 2 HfCl 6 and Cs 2 ZrCl 6 crystals. The scintillation light yields of Cs 2 HfBr 6 and Cs 2 ZrBr 6 were estimated to be 61,500 and 37,200 photons/MeV, respectively, which are much higher than those of Cs 2 HfCl 6 and Cs 2 ZrCl 6 crystals.
