“…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.

Glasses based on borophosphate with the formula 42.5P2O5 -42.5B2O3 -(15-x) Li2O -xMoO3 mol% where 𝑥 = (0 ≤ 𝑥 ≥ 15) were manufactured using the melt-quenching methodology.The status of prepared samples was identified by (XRD). The temperature of the glass transition Tg, the temperature of onset glass crystallisation Tc and the temperature of the crystallisation Tp were evaluated using a differential thermal analyser (DTA). The energy gap (𝐸 𝑜𝑝𝑡 ), Urbach (𝐸 𝑢 ), and parameters of dispersion were calculated through the data of optical spectra. Physical properties were determined and calculated, such as molar refractivity, metallization, electron polarizability, electronegativity, loss of reflection and dispersion parameters. Raising MoO3 at the expense of Li2O was used to assess the level of protection. For radiation protection applications, the glasses under investigation had superior characteristics.

Using melt-quenching techniques, the glass system 22SiO 2 -23Bi 2 O 3 -37B 2 O 3 -13TiO 2 À ð5 À xÞ LiF-x BaO was prepared. The amorphous status of fabricated samples were established using X-ray diffraction patterns. Differential thermal analysis (glass transition temperature, crystallization temperature, and thermal stability) as well as optical properties (molar refractivity, bandgap, molar polarizability, reflection loss, metallization, electronegativity, and electron polarizability) of these glasses have been investigated. These structural changes influence the thermal properties, as we discovered. Indeed, as BaO levels rise, all the thermal parameters rise as well. With increasing BaO content, density, and refractive index rise. Bandgap energies for direct and indirect transitions reduced as the BaO content increased while Urbach energy increases. This interpretation attributable to the increment in the bond length of Ba-O. This study suggests that the fabricated glasses' optical and thermal characteristics have improved, making them suitable for a variety of applications.
