Quaternary glasses with the composition 50SiO2-25TiO2-5La2O3-(20-x) Na2O-xY2O3 where : (0 ≤ ≥ 10) were synthesized using the melt-quench technique. XRD examined the nature of prepared glasses. UV-spectroscopic of investigated glass system studied at room temperature. Both optical bandgap and refractive index of the present glass have been increased. The polarizability and basicity were determined. Thermal parameter values increased as Y2O3 increased. Under controlling heat, the glass-ceramic were prepared and confirmed using XRD. Glass-ceramics are examined using SEM to evaluate a microstructure. Ultrasonic velocities and elastic-moduli of glass-ceramic samples are increased because of the increase in internal energy. The role of Y2O3 modifier in the glass system is clearly demonstrated. Y2O3 also works as an excellent nucleating agent that can induce crystallizations, supporting in the creation of the sub-phase of glass-ceramics.

The techniques of melt-quenching were used to generate 53B2O3 -2NaF -27PbO -(20 − )BaO -La2O3 (0 ≤ ≥ 15) . XRD patterns have established the amorphous character of glass samples. There is clear evidence of the role of La2O3 modifier in the glass network. The thermal characteristics were identified to increase with an increase in La2O3 content. Increasing La2O3 increases the linear and non-linear optical bandgap energy and the Urbach energy. By adding La2O3 to the glass samples, the refractive index, molar polarizability, polarizability, and optical basicity are increased. Theoretically, the bulk modulus and the glass transition temperature increase because of the increase in bond strength. The number of bonds per unit increased with the increase in La2O3 content because of the modifier character of La2O3 in the glass samples. Multiple optical parameters ( ∞), ( o),(1) , ( 3) ) and ( 2 ) as a function of linear and non-linear were obtained. The extent of shielding in this article was examined with the increment in La2O3 at the expense of BaO. The results correspond with similar studies conducted previously.

“…Glasses doped intermediate oxides such as TiO2 and Y2O3 have specific mechanical and optical characteristics such as hardness, elastic moduli, and higher refractive index [15][16][17][18][19][20][21]. It is also significant to observe that the inclusion of Y2O3 improves the capability of UV transmission, enhances thermal stability and chemical durability.…”

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.
