摘要：

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 (SCs) of Ce3+ doped LuAG using the technology of liquid phase epitaxy (LPE). We show the possibility of the simultaneous registration of alpha-particles and gamma-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 a-particles of Am-241 (5.5 MeV) source and gamma-quanta of Cs-137 (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 a-particles and gamma-quanta.
