摘要：

Scintillating properties of Ce3+-doped (Lu,Y) aluminum garnet single crystalline films (SCF) were investigated. Thin SCF films of thickness between 1 and 30 gm were grown by a liquid phase epitaxy (LPE) method in various fluxes. The alpha-particle excitation (mainly 5.4857 MeV line of Am-241) of pulse height spectra is used to measure scintillation response of SCF, especially peak of those alpha-rays which are totally absorbed in the films. Detailed studies and evaluation of scintillation measurements of large sets of Ce3+-doped SCF (Lu,Y) aluminum garnets showed that at present time (i) YAG:Ce SCF have comparable scintillation properties as YAG:Ce single crystals, especially their N-phels photoelectron yields are the same while (ii) scintillation properties of LuAG:Ce SCF do not reach those of LuAG:Ce single crystal.
