摘要

A novel series of Bismuth–Barium Tellurite glasses doped with samarium ions has been produced by traditional melt quenching with the composition of xSm2O3 + (10−x) Bi2O3 + 20Bao + 70TeO2, where x = 0, 1, 2, 3, 4, and 5 mol% (TBaBiSmN). X-ray diffraction (XRD) studies verified the nature is amorphous. The Raman Spectroscopy and FTIR study reveals the structural properties. The glass's thermal properties were examined with TG-DSC to reveal the prepared glasses' thermal stability. Various physical parameters were calculated. Optical band gaps were determined with absorption spectral data. The absorption spectrum was noted in the wavelength range between 200 and 1100 nm to assess the glass's optical properties. The glass density was computed using Archimedes' theory, and the associated molar volume was also estimated. Density rises with the rise in Sm2O3 concentration, and the molar volume is inversely related to the glass density.
