Abstract

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

LaI 3 :Ce 3+ has the smallest band gap in the LaX 3 :Ce 3+ (X=F, Cl, Br, I) series and hence a potentially higher scintillation yield. The luminescence properties of LaI 3 :Ce were investigated by means of optical, X-ray, and g-ray excitation. Unexpectedly, the compound is a poor scintillator at roo
