Optical and scintillation properties of pure Cs2HfCl6 (CHC) 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 Bridgeman method showed light output of 37,000andplusmn; 2,000 photons/MeV . The FWHM energy resolution was determined to be 3.7andplusmn; 0.5andtimes; (E/662 keV)-0.85andplusmn; 0.03[%], where E [keV] is the gamma-ray energy. Moreover, the temperature dependence of the light output was stable from -5 to 30 -C, while the light output increased below -10 -C.
