What is Radio- and thermoluminescence and energy transfer processes in Ce3+(Tb3+)-doped phosphate scintillating glasses about?

Ce 3+ and Tb 3+ -doped Na(K)-Gd phosphate glasses were synthesized and their radio-, photo-and thermoluminescence properties were investigated. Increased radioluminescence e ciency with respect to Gd-free glass matrix has been achieved at Gd concentrations above 20 mol%. This is explained by e cient capture of thermalised electrons and holes in the Gd 3+ -sublattice resulting in the formation of Gd 3+ excited states followed by Gd 3+ -Gd 3+ energy transfer and single-step transfer to the Ce 3+ (Tb 3+ ) emission centres. In such a way non-radiative losses in the phosphate glass matrix are reduced. Energy migration in Gd-sublattice becomes frozen below 10 -15 K due to local ÿeld uctuations in the glass matrix. Thermoluminescence measurements above room temperature show the presence of two groups of traps with concentrations strongly dependent on the glass composition.
