This paper describes the synthesis and spectroscopic studies of the glass system, 20Na2O-(20-x) ZnO-xZnF2-60B2O 3 (x = 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 MAS-NMR shows the presence of sharp peak around -14 ppm. From the IR studies, the broadening of the peak around 1200-1400 and 800-1100 cm -1 shows the presence of mixed linkages like B-O-B, B-O-Zn in the network. © Indian Academy of Sciences
