Abstract
A single crystal of Gd1.9Y0.1SiO5:0.5%Ce (GYSO:Ce) was grown using the Czochralski method and its structure, photoluminescence, and scintillation properties were analyzed. Based on Rietveld structure refinement, we found that mixing with Y5at% changed the host structure very little. Two typical types of cerium emission, i.e., Ce1 and Ce2, were confirmed based on the photoluminescence excitation and emission spectra at 77â¯K. The energy transfer of Gd 6PJâCe1 probably explains the slow component in the photoluminescence and scintillation processes. The light yield of the GYSO:Ce sample was determined as 11200â¯ph/MeV and the energy resolution was 8.6%. The afterglow intensity of GYSO:Ce was relatively low.
