This work focuses on the spectroscopic study of RE3+ ion, namely, trivalent neodymium (Nd3+) doped lead borotellurite glass with a composition of TeO2-B2O3-PbO. The glass sample has been prepared by conventional melt-quenching technique. The density, molar volume and optical energy band gap of these glasses have been measured. The refractive index, molar refraction and polarizability of oxide ion have been calculated by using Lorentz-Lorentz relations. The absorption spectra are recorded using UV-Vis-NIR spectrometer in the range of 200-900 nm.
