Investigation on the influence of cerium doping form on the luminescence properties of Lu0.8Sc0.2BO3 scintillation crystals
Abstract
Transparent Lu0.8Sc0.2BO3:Ce single crystals doped with different forms of cerium [CeF3, CeO2 or Ce(NO3)3] were grown by the Czochralski method. The influence of cerium doping form on the luminescence mechanism, point defect and scintillation efficiency of Lu0.8Sc0.2BO3:Ce was investigated and discussed in detail. We found that the cerium doping form had no influence on the luminescence mechanism and the type of point defects in Lu0.8Sc0.2BO3:Ce host. The underlying reason for the scintillation efficiency discrepancy in these singlecrystall samples was revealed by
