摘要：

SnO-ZnO-P2O5 glasses with 30 and 40 mol% P2O5 were prepared by a melting process in an air atmosphere. The glass transition temperature, refractive index, and photoluminescence of the glasses were investigated. The electronic states of Sn(II) and Sn(IV) were determined by Mossbauer spectroscopy. The PO4 units were investigated by Raman spectroscopy. The glass transition temperature was lower than 450 degrees C. and decreased as the Sn concentrations increased, so that the minimum was about 250 degrees C. The refractive index increased as the Sn concentration increased. The emission spectra of the glasses peaked at around 2.0-3.0 eV and depended on the glass compositions. (C) 2012 Elsevier B.V.
