Abstract: This paper described the influence of annealing process on X-ray irradiation excited emission spectra, transmission and radiation hardness of PWO crystals grown by a modified Bridgman method. The results show the scintillation properties and radiation hardness of PWO crystals annealed in the atmosphere with oxygen-rich and suitable temperatures are improved obviously.

Key words: lead tungstate crystal, scintillation properties, annealing procedure
