Crystal growth and optical properties of Ce-doped (La,Y)2Si2O7 single crystal

Research output: Contribution to journalArticlepeer-review


We have grown Ce-doped (La,Y)2Si2O7 single crystal by micro-pulling-down method and investigated its optical and scintillation properties. We have successfully prepared the single crystal with (Ce0.015La0.600Y0.385)2Si2O7 composition. The observed thermal quenching process could be characterized by the quenching temperature (T50%) of 526 K and its activation energy was determined to be 0.62 eV. Further considering the thermal quenching factors, it was found that the thermal quenching was caused by at least the thermal ionization and maybe also by classical thermal quenching. The light output and scintillation decay time were evaluated to be ~12,000 photons/MeV and ~42 ns, respectively. These results indicate that (Ce0.015La0.600Y0.385)2Si2O7 has a great potential for application in scintillation materials.
