| الوصف: | The influence of the Mg2+ codoping and annealing in the air on the scintillation and luminescence characteristics of Pr-doped lutetium-aluminum garnet crystals (LuAG) was studied to find a possible positive effect of Pr4+. The overall scintillation efficiency under X-ray excitation of the annealed Pr- doped samples decreased with increasing Mg concentration. This was explained by increased overlap of the Pr3+ 5d-4f emission with the charge-transfer (CT) absorption band of the Pr4+ ion stabilized by Mg2+. Unlike for the Ce-doped analogs, promoting the Pr3+ luminescence center to the tetravalent state by divalent ion co-doping and air annealing did not improve scintillation properties of Pr-doped LuAG. |
