Growth and Optical Uniformity of Large Size Y:PbWO4 Crystal Grown by the Bridgman Method

Abstract

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.

Key words: large size, Y:PbWO4 crystal, growth, uniformity
