| Abstract: | In this paper, we grew high optical quality PbWO_4 and La3+,Mg2+, Mo6+ and Bi3+ Doped PbWO_4 single crystals with the size 20-25mm diameter and 25-30mm long by Cz method. The x\|ray diffraction spectra, transmission spectra, excitation spectra and emission spectra, light yield, radiation hard and decay time have been measured. We summarized and explained the doped effects on scintillation properties of PbWO_4 crystals and effect of annealing in O_2 on radiation hard properties. We discussed the possibility of improving its scintillation properties by doping. |
