Our group investigated the effect of Na doping to Cs₂HfCl₆ single crystal scintillator in order to improve its decay time. Cs₂HfCl₆ single crystals were grown by vertical Bridgman method. In this presentation, we will present the results and discussions of grown crystals, powder X-ray diffraction, lattice constants, and luminescent properties.
