A Study of Thermal, and Optical Properties of 22SiO2- 23Bi2O3-37B2O3-13TiO2-(5-x) LiF- x BaO Glasses

Abstract

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.

Investigation of BaO reinforced TiO2–p2O5–li2O glasses for optical and neutron shielding applications

“…Because of the pair creation interaction, the (Z eq ) value decreases at energies higher than 1 MeV. [36][37][38][39][40][41][42][43][44][45] As a result, glass with a higher BaO content has a higher Z eq than others. In all photon energy, it was discovered that G 5 has the maximum values, while G 1 has the smallest.…”

Effect of CeO2 /Er2O3 co-doping on spectroscopic properties of zinc fluoroborate glasses

“…The effects of inclusions that modify glass, such as halide ions (ZnF2), as well as structural alterations brought on by BO3/BO4 ratios, were carefully examined [16][17][18][19][20]. ZnO is a well-known material due to its low cost, non-toxicity, and environmental friendliness.…”
