Název v původním jazyce

Composite scintillators based on the crystals and single crystalline films of LuAG garnet doped with Ce3+, Pr3+ and Sc3+ ions

Popis výsledku v původním jazyce

This work is devoted to the development of new types of advanced composite scintillators based on the single crystalline films (SCFs) of Lu3Al5O12 (LuAG) garnet, doped with Pr3+ and Sc3+ ions, and substrate from single crystals of Ce3+ doped LuAG using the technology of liquid phase epitaxy. We show the possibility of the simultaneous registration of α-particles and γ-quanta by means of separation of the decay kinetics of SCF and crystal parts of such composite scintillators. Namely, the significant differences in the pulse height spectra and the scintillation decay kinetics of LuAG:Pr SCF/LuAG:Ce SC and LuAG:Sc SCF/LuAG:Ce SC composite scintillators under excitation by α–particles of 241Am (5.5 MeV) source and γ-quanta of 137Cs (662 keV) source are observed. For these reasons, such types of composite scintillators can be applied for separation of the signals coming from their film and crystal parts at the registration of the mixed radiation fluxes of α-particles and γ-quanta.
