    Cesium hafnium chloride of formula Cs2HfCl6 (CHC) was discovered as a scintillating material by Bryan and Ferranti in 1984 and recently it was identified by Burger et al. as a promising scintillator for gamma spectroscopy. The aim of this work is a preparation of high quality and purity CHC material and its subsequent crystal growth by vertical Bridgman method. Prepared crystals were characterized using X-ray fluorescence and X-ray diffraction analyses to determine the purity and phase content, respectively. Moreover, the optical characterizations: the absorption, radioluminescence, and photoluminescence spectra, as well as decay measurements on prepared optical specimens from grown crystals, were performed.
