Ce3+ doped crystalline garnet films - scintillation characterization using alpha particle excitation

Abstract

Scintillating properties of Ce3+ -doped (Lu,Y) aluminum garnet single crystalline films (SCF) were investigated. Thin SCF films of thickness between 1 and 30 microns were grown by a liquid phase epitaxy (LPE) method in various fluxes.

The alpha-particle excitation (mainly 5.4857 MeV line of 241 Am) 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.
