Structural and functional modifications in CeO2-doped borosilicate glasses: insights into dielectric behavior and gamma radiation attenuation
The purpose of this work is to examine how the insertion of cerium oxide (CeO<sub>2</sub>) impacts the borosilicate glass system's structure, dielectric, as well as radiation attenuation characteristics. As the CeO<sub>2</sub> quantities expand from 0.0 to 1.0 mol%, the glass's density gradually rises between 2.9517 and 3.1526 g.cm<sup>- 3</sup>. Additionally, the structural ordering process surrounding the SiO<sub>4</sub> within a glass structure is formed, and the proportion of linked boron (trigonal as well as tetrahedral cations) increases. As CeO<sub>2</sub> concentrations increase, the absolute value of a dielectric constant (ε') decreases. Ce-1.0, the sample with the highest Cerium content, has a small ε' in comparison to other Cerium contents, making it excellent for packing materials because of its fast travel speed. The Phy-X program was used examine, G<sub>Zeq</sub>, G<sub>EBF</sub>, G<sub>EABF</sub>, G<sub>Cef,</sub> G<sub>TF</sub>, and G<sub>RPE</sub> for five specimens of glass with different CeO<sub>2</sub> concentrations across a wide energy range (30-2000 keV). Ce-1.0 was found to have the highest G<sub>Zeq</sub> and the lowest G<sub>EBF</sub> and G<sub>EABF</sub> values. It was confirmed that raising the CeO<sub>2</sub> content improved the glass's defense against nuclear radiation because there are more high Z numbers (Ce-58) which raises the chance of gamma-ray attenuation.
