The energy transfer mechanism in Eu doped and Tl, Eu co-doped NaI crystals is discussed. The self-trapped exciton emission band overlaps stronger with Eu²⁺ excitation bands rather that with Tl⁺. This suggests that transfer STE -> Activator can be more efficient in Eu²⁺ co-doped NaI:Tl crystals. T...
