摘要：
We have studied the scintillation and dosimetric properties of Sn-doped ZnO-SiO2-B2O3 glasses. The glass samples were obtained by a conventional melt quenching method. In the scintillation spectra of the Sn-doped ZnO-SiO2-B2O3 glasses, emission peaks due to the 5p -> 5s transition of Sn2+ ions were observed. Scintillation decay times of the Sn-doped ZnO-SiO2-B2O3 glasses were from 2.44 to 2.95 mu s. In the thermoluminescence (TL) glow curves of the Sn-doped ZnO-SiO2-B2O3 glasses, we observed broad glow peaks at 200 degrees C. From the dose-response curve, the lower limit of detection for the 0.1% Sn-doped sample was 0.1 mGy.
