Abstract
Light yield of some Y3+: PWO crystals increases after irradiation, and is accompanied with transmission change in the wavelengths from 380 to 500 nm. The pre-existing 430 nm color centers or annealing induced ones are unstable during irradiation. These results interpret the temperature sensitivity of light yield and radiation hardness. A proper annealing temperature and the way to eliminate the instability are found out.
