Abstract
Neodymium nanoparticle (Nd³⁺ NPs) incorporated 40B₂O₃-(30-x)TeO₂-15Y₂O₃-15Na₂O-xNd2O3 glasses via melt quenching technique. The amorphous structure of these glasses was established by X-ray diffraction (XRD) studies. The glasses were explored for density measurements by Archimedes' method using toluene as the immersion liquid and density was found in the range between 2.92 and 3.34 g/cm³. Optical band gaps were studied by UV-visible spectroscopy. Indirect bandgap observed in the range from 3.70 to 4.17 eV. Whereas the refractive index varies from 2.14 to 2.23. the correlation and comparable pattens were seen in the optical bandgap values derived from the ASF and DASF approaches.
