Spectroscopic Properties and Dispersion Parameters of B2O3 – SiO2 – Bi2O3 – TiO2 – Y2O3 Glasses

Abstract Glasses with the chemical formula 52B2O3 – 12SiO2- 26Bi2O3 – (10-x) TiO2 - Y2O3, :(0≤ x ≥ 10), the melt-quench method was used to prepare this glass system. The purpose of this article is to investigate the spectroscopic features of these glasses. The nature of the glass system has been investigated using X-ray diffraction analysis. In the current article, the molar volume acquired decreased while the density and refractive index increased. In the current article, Y2O3 plays an important role and impacts the spectroscopic characteristics of the samples accordingly. For all the present glasses, the optical bandgap is found to be in the semiconducting range. The optical bandgap enhances as Y2O3 rises, while Urbach energy reduces. Molar Refractivity, molar polarization, polarization, and optical basicity decrease with increasing Y2O3 content. Wemple and Didomenico principles were used for calculated the Eo and Ed dispersion. The significance of the Y2O3 modifier in the glass system signifies proved.
