    • Abstract

       

      This paper describes the synthesis and spectroscopic studies of the glass system, 20Na2O–(20–𝑥) ZnO–𝑥ZnF2–60B2O3 (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.
