The TeO 2 -B 2 O 3 -BaO-Nd 2 O 3 series of glasses was synthesized by the melt-quenching method at 1100 °C. Then, a systematic study of these glasses was carried out to determine their optical and gamma-radiation shielding performance. The optical transmission of the glass evaluated using UV-Vis absorption spectroscopy showed significant absorption of UV light within a range of approximately 340 nm - 370 nm, and many Nd 3+ f-f transitions were noted at various wavelengths between 400 nm - 900 nm (except 431 nm, 475 nm, 514 nm, 586 nm, 683 nm, 748 nm, and 805 nm). Doping of Nd 3+ ions confirmed that rare-earth ions were incorporated without phase separation. In terms of optical characteristics, increased optical basicity (from 1.248 to 1.259) and decreased optical electronegativity (from 0.903 to 0.882) were observed as the Nd 2 O 3 concentration increased, indicating increased electron-donating ability and polarizability of the glass network. An evaluation of the gamma-ray shielding features of the prepared glasses at 0.015–15 MeV was performed using the Phy-X/PSD software. The linear attenuation coefficient (LAC) for Te21Nd3 had the highest value of 118.56 cm -1 at 0.015 MeV, compared to a value of 91.59 cm -1 for the undoped glass. Based on these observations, tellurite glasses that are rich in Nd will interact with more of the incoming radiation than tellurites that contain lower amounts of Nd. The combination of high optical response and high radiation attenuation properties of the Te21Nd3 composition makes this glass composition well-suited for use as a transparent material for advanced radiation shielding applications.
