Modification of halide μ-PD apparatus by custom made elements allowed us to grow cesium hafnium chloride (CHC) by vertical Bridgman method with significantly reduced growth time. Structural and optical properties of samples prepared from as-grown crystals were studied and compared to crystals grown by standard VB method. The X-ray diffraction confirmed the formation of cesium hafnium chloride single-phase and natural cleavage of the crystals along the (1 1 1) crystallographic plane. Photoluminescence emission, excitation, absorption, and radioluminescence spectroscopy revealed that the optical quality of the crystals grown by the modified VB method was comparable to the quality of the crystals grown by standard VB method. This setup allows the time and cost-effective material screening and it is a powerful tool for the development of new halide based single crystal scintillators.
