Annotation	This work was focused on the preparation of starting materials (CsCl, HfCl4), synthesis of Cs2HfCl6, doping of Cs2HfCl6 by tetravalent elements A4+ (such as Zr4+), and growth of Cs2HfCl6:Zr4+ crystals by the vertical Bridgman method. Prepared crystals were cut and polished for subsequent examination concerning their physical, structural, optical, luminescence, and scintillation properties. The grown crystals exhibited emission originating in the self trapped exciton localized on the Hf and Zr centers. Due to that red shift of the observed emission was recorded with increasing Zr content.
