| Abstract: | In the paper, the status of R&D on PbWO4 single crystal, a new type of heavy scintillator, is reviewed. Some problems emerged from R&D period, such as the diversity of luminescence behaviors, the peculiarity of transmission spectra and radiation resistivity, crystallographic structure modification and the vaporization of constituents of PbO and WO3 are focused. Additionally, several proposed mechanism on green luminescence of the crystal are discussed. |
