Abstract

An intense optically stimulated luminescence (OSL) was observed, for the first time, in x-ray irradiated xSnO–(25−x)SrO–75B2O3 glass. It was found that the peak wavelength of OSL emission spectrum and its stimulation spectrum is about 400nm and 600nm, respectively. The OSL intensity is depended on the SnO contents (x=0.05–1.5 ) and the most intense OSL was observed in 1.0mol% SnO doped glass. It was found that the OSL intensity is increased with increasing x-ray absorbed dose. Fairly good fading characteristics were observed in the x-ray irradiated glass, showing that this glass is useful as a candidate for OSL sensor materials for ionizing radiation monitoring.
