Abstract
- We study Ce3+ luminescence and scintillation characteristics in novel, high performing hosts among the oxide single crystal scintillators, the La-admixed Gd2Si2O7. Obtained characteristics are systematically compared with the earlier studied Lu2Si2O7 host. We determine the barrier height of the thermal ionization of the Ce3+ excited center, we address the effect of La-admixture on the physical characteristics, and we construct an energy level diagram of the material system. High scintillation efficiency, low afterglow, and the onset of Ce3+ excited state ionization appearing well above room temperature indicate a large potential of La-admixed Gd2Si2O7 in a variety of scintillating material applications.
