“…Considering the importance of sodium titanium silicate glasses in scientific and technological, characteristics like ionic conductivity in power generation glasses modified with various oxides are strongly required [20][21]. In contrast, the incorporation of transitional or rare earth oxides into sodium titanium silicate glass structures are enhanced optical, electrical, thermal, mechanical and radiation protection characteristics [22][23][24][25]. Glasses containing rare-earth ions have attracted a great deal of interest because of their benefits [26][27][28][29][30][31].…”

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.

“…It has been reported that spectral UV-absorption is increasingly absorbed. Therefore, La2O3 is accountable for the slight growth of BO [24][25][26][27][28][29][30][31][32][33][34][35][36]. Absorption coefficient of the glasses exemplifies Fig.…”

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.

“…Moreover, these glasses can be considered as transition metal ion (TMi) to manufacture super-efficient optical and luminescence components. Furthermore, the presence of (TM) in different valences gives the silicate glasses a broad range of scientific and technological importance to use for many applications in various fields [9][10][11][12][13][14][15][16][17].…”

In this research, we prepared zinc lead silicate glass system with the composition 35Pb3O4-60SiO2-(5-x) ZnO-xWO3 (0 ≤ x ≤ 5 mol %) via the melt-quench method. XRD is explored the nature of the glass system. Ultrasonic velocity, and elastic modulus were experimentally investigated and then the results were confirmed by using the theoretical calculations. It was found that because of molar volume reduction inter-ionic distance , polaron radius , and internuclear distance, of the investigated glasses are reduced with WO3 content. The basic attenuation factors; mass and linear coefficients denoted by µ/ρ and µ, respectively, were determined employing several simulations for each energy via FLUKA code. As WO3 content increased from 0 to 5 mol %, the µ increased from 0.728 cm -1 to 0.856 cm -1 achieving high shielding performance for the sample with x = 5 mol %. At 0.6 MeV with x = 5 mol %, we found that the dose rate of the prepared glass system decreases from 2.35 × 10 7 R/h at 1 mm to 4.71 × 10 6 R/h at 4 mm. The values of MFP and HVL are lower than those of the conventional photon shields indicating that our prepared glass samples (especially G5 glass sample) have promising shielding properties to use for x/gamma rays applications.
