N2 - Six glass samples composes the (70-y) B2O3-15TeO2-10Na2O-5PbO-yEu2O3, where y = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5 mol%, have been synthesized by conventional melt quenching technique. The properties such as the structural, thermal and spectroscopic properties were studied by employing the suitable characterizations tools, such as X-ray diffraction, differential scanning calorimetry, Raman spectroscopy, fourier transform infrared spectroscopy, magic angle spinning nuclear resonance spectroscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy. The XRD, SEM and EDS confirm non-crystalline nature, microstructural and homogeneous, absence of impurity of glass samples, respectively. The DSC data reveals the good thermal stability of glasses. The FT-IR and Raman studies reveal the contribution of boron and tellurium in the network of prepared glasses, the presence of BO3, and BO4, a small amount of six-member boroxol rings, TeO3 and TeO4 structural groups. The MAS-NMR studies reveal the presence of quadrupolar interaction of BO4 and quadrupolar broadening of BO3 in all glasses and it also discloses the fact that only a small amount of BO4 is converted into BO3 during structural evolution.
