Growth of Tm3+-Doped Y2O3, Sc2O3, and Lu2O3 Crystals by the Micropulling down Technique and Their Optical and Scintillation Characteristics
Single -crystal growth of Tm3+-doped Y2O3, Sc2O3, and Lu2O3 sesquioxides, with a melting point around 2400 °C, by the micropulling down technique is reported. Crystal quality and composition of the crystals were evaluated by rocking curve and energy-dispersive X-ray (EDX) analyses, respectively. Opt...

Zusammenfassung: | Single -crystal growth of Tm3+-doped Y2O3, Sc2O3, and Lu2O3 sesquioxides, with a melting point around 2400 °C, by the micropulling down technique is reported. Crystal quality and composition of the crystals were evaluated by rocking curve and energy-dispersive X-ray (EDX) analyses, respectively. Optical properties including optical transmittance and photoluminescence decay profiles were also examined. Furthermore, scintillation performance of the crystals including pulse height spectra and radio-luminescence spectra under α-ray and γ-ray excitation was evaluated. |
