Growth and Optical Uniformity of Large Size Y:PbWO_4 Crystal Grown by the Bridgman Method

Bo Gong

Abstract

The crystal growth technique of large size Y:PbWO4 crystal by the Bridgman method was discussed. The technical methods to eliminate cracks of the crystal and constitutional super- cooling were presented. Y:PbWO4 crystal with the size of 55mm×55mm×250mm was successfully made. The transmittance spectra and radioluminescence spectra at different positions along crys- tal growth orientation were measured and studied. The results show that the large size Y:PbWO4 crystal has good optical uniformity.
