Optical and scintillation properties of pure Cs2HfCl6 single crystals were investigated. In particular, light output and energy resolution were measured using a Si avalanche photodiode (Si-APD), since the Si-APD has sufficient quantum efficiency of around 70 % at emission wavelength region of CHC around 420 nm. This CHC single crystal grown using the vertical Bridgman method showed light output of 37000 photons/MeV. Moreover, the temperature dependence of the light output was stable from -5 to 30°C, while the light output increased below -10°C.
