Luminescence Spectra and Radiation Induced Color Centers for Lead Tungstate Crystals

Abstract

Abstract: The luminescence spectra and radiation induced color centers of undoped and various doped lead
tungstate crystals were studied. The radiation induced color centers in all samples (excluding the undoped and Sb doped samples) may be
decomposed into two kinds of color centers peaked at 400 and 500nm, respectively. For undoped samples, the peaks of radiation induced color
centers are at 360 and 530nm, and those of Sb doped samples are at 350 and 430nm. These two kinds of color centers are located at two
sides of the luminescence spectra and with different damage and recovery constants.

Key words: lead tungstate, color center, luminescence spectra
