Single crystal of the mixed-halogen compound Cs2HfCl3Br3 was grown by the vertical Bridgman method, and we investigated its crystal structure and optical properties. Single-crystal X-ray diffraction and energy dispersive Xray spectroscopy analyses indicated the chemical composition to be approximately Cs2Hf(Cl0.58Br0.42)6. The emission peak of Cs2HfCl3Br3 was red-shifted by Br substitution, and the photoluminescence decays of Cs2HfCl3Br3 were accelerated when compared to those of Cs2HfCl6.
