Growth of large-size crystal of PbWO4 by vertical Bridgman method with multi-crucibles

Abstract In this paper, we report the crystal growth of large-size lead tungstate (PbWO 4 ) crystals by modified vertical Bridgman method with multi-crucibles. The growth conditions were also studied and optimal growth parameters were obtained. The uniformity of grown PbWO 4 and the impurities in grown PbWO 4 were analyzed by glow discharge mass spectroscopy method. The measurements of lattice parameters and phase analysis were carried out by X-ray diffraction. The scintillation properties of grown PbWO 4 crystals were investigated.
