在空气气氛中用熔融法制备了含30%和40%P_2O_5的SnO-ZnO-P_2O_5玻璃。研究了玻璃的玻璃化转变温度、折射率和光致发光。用穆斯堡尔谱测定了锡(II)和锡(IV)的电子态。用拉曼光谱对PO4单元进行了研究。玻璃转变温度低于450℃，并随锡浓度的增加而降低，最低为250℃左右，折射率随锡浓度的增加而增大。玻璃的发射光谱在2.0-3.0 eV附近达到峰值，并与玻璃成分有关。
SnO–ZnO–P2O5glasses with 30 and 40mol% P2O5were 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 Mössbauer spectroscopy. The PO4units were investigated by Raman spectroscopy. The glass transition temperature was lower than 450°C, and decreased as the Sn concentrations increased, so that the minimum was about 250°C. The refractive index increased as the Sn concentration increased. The emission spectra of the glasses peaked at around 2.0–3.0eV and depended on the glass compositions.
