Abstract
The bismuth-boro-tellurite glass has been chosen by various analysts from all around the world due to its advantages and ability the improvement of glass technologies. This paper aims to study the structural and optical properties of the bismuth-boro-tellurite glass system with different amounts of thulium oxide as a glass dopant. Four glass sample from chemical composition of [(B2O3)0.25 (TeO2)0.75]0.75 [(Bi2O3)0.25]1-x [Tm2O3]x (x = 0.000, 0.005, 0.010, and 0.015 mol%) were prepared by melt-quenching method with suitable melting and quenching temperature. The Ultraviolet-Visible Spectroscopy (UV-Vis) was used for recording their optical absorption spectra. These optical absorption spectra were used to determine the optical band gap energy, refractive index, and polarizability of all glass samples. While the structural changes are observed using X-ray diffractometer (XRD) and Fourier Transform Infrared Spectroscopy (FTIR).
