Abstract
- We synthesized 20Lu<subscript>2</subscript>O<subscript>3</subscript>-30Ga<subscript>2</subscript>O<subscript>3</subscript>-50SiO<subscript>2</subscript> glasses doped with various concentrations of Sn using a floating zone furnace equipped with Xe arc lamps. The samples showed a luminescence band around 450 nm in both photoluminescence (PL) and scintillation spectra. The origin of the luminescence was ascribed to the T<subscript>1</subscript>-S<subscript>0</subscript> transition of Sn<superscript>2+</superscript> on the basis of the luminescence wavelength and PL decay time constant. The highest scintillation intensity and PL quantum yield were observed from the 1% Sn-doped sample. The afterglow level tended to decrease with increasing Sn doping, and the afterglow levels of the 1 and 3% Sn-doped samples were comparable to that of the conventional Tl-doped CsI scintillator. The optimal concentration of Sn for the glass was estimated to be 1%. [ABSTRACT FROM AUTHOR]
