Improvement of Luminescent Properties of PbWO4 by Doping with Gd3＋ Ions
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 d...

| description | 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. |
