Abstract
A computer simulation study has been performed to investigate the defects in PbWO4(PWO). The formation energies of isolated point defects VPbâ³, VO·· and cluster defect VPbâ³-VO·· pair have been calculated. It is theoretically demonstrated that the most of VO·· in the as-grown PWO crystal exists in the form of the vacancy pair VPbâ³-VO··, which plays an important role in the formation and transformation process of light induced color centers in the PWO crystal.
