Determine the physical origin of luminescence trapping sites in undoped and cerium-doped rare-earth and yttrium oxyorthosilicates.
Compared thermally stimulated luminescence glow curves of undoped Lu2SiO5 and Ce3+-doped oxyorthosilicates exhibiting the monoclinic C2/c structure.
Measured optical absorption spectra of pristine Lu2SiO5 before and after exposure to x-ray irradiation.
Observed matching thermally stimulated luminescence glow curves between undoped Lu2SiO5 and Ce3+-doped oxyorthosilicates, confirming that carrier traps are intrinsic to the host lattice rather than induced solely by dopants.
Identified intrinsic absorption centers in pristine Lu2SiO5 that intensify after x-ray irradiation, demonstrating the presence of oxygen-related point defects.
