Photo- and Radioluminescence of Ce3+-Doped Dense Oxide Glass

Photo-and radioluminescence characteristics of Ce3+-doped dense oxide glass (SiO2-B2O3-Al2O3-Gd2O3) are presented. The Gd3+→ Ce3+ energy transfer was evidenced by photoluminescence excitation spectra of Ce3+ emission. Photoluminescence decay kinetics was governed by a few tens of nanoseconds decay t...

Zusammenfassung:Photo-and radioluminescence characteristics of Ce3+-doped dense oxide glass (SiO2-B2O3-Al2O3-Gd2O3) are presented. The Gd3+→ Ce3+ energy transfer was evidenced by photoluminescence excitation spectra of Ce3+ emission. Photoluminescence decay kinetics was governed by a few tens of nanoseconds decay time. The integral scintillation efficiency of about 22% of that of the Bi4Ge3O12 scintillator was obtained under X-ray irradiation. Scintillation light yield under alpha particle excitation was measured and compared with that of the Bi4Ge3O12 crystal.
