Luminescence and scintillation characteristics of YAG:Ce single crystalline films and single crystals

摘要

The detailed comparative analysis of luminescent and scintillation properties of the single crystalline films (SCF) of YAG:Ce garnet grown from melt-solutions based on the traditional PbO-based and novel BaO-based fluxes, and of a YAG:Ce bulk single crystal grown from the melt by the Czochralski method, was performed in this work. Using the ~(241)Am (α-particle, 5.49 MeV) excitation we show that scintillation yield and energy resolution of the optimized YAG:Ce SCF is fully comparable with that of the YAG:Ce single crystal analogue.
