| 英文摘要 | 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., Cel and Ce2, were confirmed based on the photoluminescence excitation and emission spectra at 77 K. The energy transfer of Gd P-6(J)-> Cel probably explains the slow component in the photoluminescence and scintillation processes. The light yield of the GYSO:Ce sample was determined as 11200 ph/MeV and the energy resolution was 8.6%. The afterglow intensity of GYSO:Ce was relatively low. |
