CURRENT STATUS OF R&D ON PbWO_4 CRYSTAL -A NEW TYPE OF HELY SCINTILLATOR

综述新型闪烁晶体PbWO_4（PWO）的研究现状着重评论其中的不同发光表现、透射光谱和抗辐照损伤的个体差异、晶体结构和组分挥发等。

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.
