This research examined the structural and optical characteristics of neodymium-doped magnesium borotellurite glasses with the composition of (60−x)TeO2–30B2O3–10MgO–x(Nd2O3), with x = 0, 1, 2, 3, and 4 mol%. Glass samples were prepared using the melting and quenching method. The density of the samples rose from 3.97 g/cm3 to 4.10 g/cm3 with Nd2O3 concentration. The molar volume, on the other hand, illustrated an opposing trend, and it decreased from 30.42 cm3/mol to 29.50 cm3/mol and then increased to 31.13 cm3/mol. XRD analysis showed evidence of the amorphous structure of glasses, and the Urbach energy peaked at MBTNd-2, whereas the optical band gap reached its lowest value at MBTNd-1 (direct: 3.291 eV; indirect: 2.356 eV), then increased to higher Nd concentrations. Photoluminescence analysis revealed prominent emission peaks at 444, 488, 545, and 614 nm under 400 nm excitation, with MBTNd-4 exhibiting the strongest intensity. Chromaticity analysis showed all doped samples fall within the blue region, indicating suitability for photonic applications. These findings demonstrate that Nd2O3 effectively enhances the optical performance of magnesium borotellurite glasses, making them viable for optoelectronic devices.
