Influence of vacuum annealing on properties of PbWO4 crystals

Abstract Transmittance and luminescence measurements of Bi-doped and Nb-doped PbWO 4 crystals after vacuum annealing were performed. Annealing effect on the optical and scintillation properties of the crystals was detected at various annealing temperatures. The gamma radiation damage is presented at different absorbed doses to investigate radiation resistance after annealing.
