The aim of this work is to investigate the influence of shallow traps on scintillating properties of YAlO3 : Ce.

Abstract

The aim of this work is to investigate the influence of shallow traps on scintillating properties of YAlO3 : Ce. Wavelength-resolved thermally stimulated luminescence measurements following X-ray irradiation at 10 K have been performed on both undoped and Ce-doped crystals. Different and composite glow curves and emission spectra were obtained. Following glow peaks analysis of YAlO3 : Ce, their room temperature decay time was evaluated to be of the order of 10-4 s. The presence of an athermal tunneling recombination process between traps and Ce3+ ions below 100 K has been evidenced by phosphorescence decays. © 2008 IEEE.
