Abstract
Single crystalline Sc, Pr, Ce co-doped Lu3Al5O12 garnet layers were grown by liquid phase epitaxy. The Sc doping increases the scintillation response of Pr3+ activator ions because of overlap of the Sc-related emission around 275 nm with the 4f→5d absorption band of Pr3+ centers.
The radioluminescence (RL) spectra give evidence for presumed energy transfer form Sc3+ to Pr3+ activator ions. Significant increase of the RL emission output was observed when co-doping with both Pr and Sc ions compared to Sc-free samples.
