Abstract
The tellurite glasses doped with Nd3+ ion were prepared with the compositions (55-x)TeO2-10ZnF2-35BaO-xNd2O3 (where x = 0.00, 0.05, 0.10, 0.50 1.00 and 1.50 mol%) by the normal melt quenching technique and characterized the spectroscopic properties. The spectroscopic properties of tellurite glasses measured from the absorption and emission measurements with Judd-Ofelt analysis. The X-ray diffraction (XRD) pattern confirms the amorphous nature. UV-Vis-NIR absorption spectra of tellurite glasses divulged nine significant peaks. The absorption peaks slightly increase with increasing of Nd3+ concentration. The NIR emission spectra at 1069, 1341 nm have been registered for Nd3+ in tellurite glasses, which corresponds to the transitions originating from 4F3/2 level to the 4I11/2 and 4I13/2 levels of Nd3+ ion, respectively, under the excitation of 523 nm. The results indicate that the prepared glass system could be a suitable candidate for using it as laser gain media around 1069 nm.
