【 摘 要 】

This paper describes the synthesis and spectroscopic studies of the glass system, 20Na₂Oâ€�??(20â€�?�ð�?��?) ZnOâ€�?�ð�?�¥ZnF₂â€�??60B₂O₃ (ð‘�? = 0, 5, 10, 15, 20), prepared by melt quenching method. The analyses of DSC and XRD did not show the crystallinity of the glass sample. ¹¹B MASâ€�?�NMR shows the presence of sharp peak around â€�??14 ppm. From the IR studies, the broadening of the peak around 1200â€�??1400 and 800â€�??1100 cm^-1 shows the presence of mixed linkages like Bâ€�?�Oâ€�?�B, Bâ€�?�Oâ€�?�Zn in the network.
