Energy transfer processes in (Lu,Gd)AlO3:Ce

Abstract

In this paper, we present initial result of studies on energy transfer processes in Ce-activated Lu, Y and Gd aluminum perovskite crystals that contribute to production of scintillation light in these new scintillator materials. In particular we report and analyze emission spectra, excitation spectra, and emission time profiles under pulsed synchrotron excitation in the wavelength range of 50-300 nm.
