Abstract

Abstract: This paper presents the characterization and investigation of the optical properties on doubly-doped large PbWO₄:(Sb,Y) crystals grown by the modified Bridgman method. Based on the comparison
measurement of the optical transmission spectra, X-ray excited luminescence, photoluminescence, decay time, light yield and irradiation damage for 23mm×23mm×20mm crystal samples
cut from seed end, middle part and top end of a large PbWO₄:(Sb,Y) crystal ingot, the results show that co-doping Sb and Y can significantly improve the light yield, radiation hardness and other spectroscopic properties of PbWO₄ crystal. However, the uniformity of large PbWO₄:(Sb,Y) crystal needs to be further improved based on the comparison of measurement results.
