| 摘 要： | The luminescent properties of PbW04: Gd3 were studied. The luminescence of Gd3 in PbWO4: Gd3 was quenched. It is possible that the excitation states of Gd3 locate in the conduction band of PbW04 crystal. The luminescent intensity of the green and the blue band of PbW04 emission increases by doping with about 0.005% and 0.01% (molar fraction) Gd3 respectively. Mechanism of this enhancement of PbWO4:Gd3 luminescence is probably due to energy transfer from Gd3 to PbW04 host in the crystal. The PbW04 doped with low concentration of Gd (about 0.005% -0.01% ) is a good scintillating material.

| Abstract: | The luminescent properties of PbWO4∶Gd3+ were studied. The luminescence of Gd3+ in PbWO4∶Gd3+ was quenched. It is possible that the excitation states of Gd3+ locate in the conduction band of PbWO4 crystal. The luminescent intensity of the green and the blue band of PbWO4 emission increases by doping with about 0.005% and 0.01% (molar fraction) Gd3+ respectively. Mechanism of this enhancement of PbWO4∶Gd3+ luminescence is probably due to energy transfer from Gd3+ to PbWO4 host in the crystal. The PbWO4 doped with low concentration of Gd (about 0.005%～0.01%) is a good scintillating material. |
