摘要: Luminescence and scintillation dynamics can be extensively influenced by the energy transfer processes, which is demonstrated at three selected scintillator materials: PbWO 4 , Ce-doped aluminium garnets PrF 3 :Ce single crystals. Charge carrier retrapping processes delay radiative recombination luminescence centers in an extended time scale, makes a substantial part of generated light technically unexploitable. Correlated measurements based on time-resolved emission spectroscopy thermoluminescence are great help to evaluate these phenomena understand their microscopic origin.
