摘      要：The luminescent properties of PbWO 4∶Gd 3+ were studied. The luminescence of Gd 3+ in PbWO 4∶Gd 3+ was quenched. It is possible that the excitation states of Gd 3+ locate in the conduction band of PbWO 4 crystal. The luminescent intensity of the green and the blue band of PbWO 4 emission increases by doping with about 0 005% and 0 01% (molar fraction) Gd 3+ respectively. Mechanism of this enhancement of PbWO 4∶Gd 3+ luminescence is probably due to energy transfer from Gd 3+ to PbWO 4 host in the crystal. The PbWO 4 doped with low concentration of Gd (about 0 005%～0 01%) is a good scintillating material.
