Abstract
Applying the melt-quenching method, lithium strontium boro-fluoride glasses with the chemical formula 22Li(2)O-28SrF(2)-(50-x)B2O3-xCeO(2)-xYb(2)O(3): (x = 0-1 mol%) were created. The material's physical characteristics, optical properties, and radiation-shielding abilities have been investigated. As the oxides molar fraction [CeO2 + Yb2O3] increased from 0.0 mol% for CY0 sample to 2.0 mol% for CY7 sample, the density increased from 2.4582 to 4.6587 g.cm(-3). In the glass structure, the oxygen-molar volume (OMV) dropped from 18.10785 to 10.09772 cm(3).mol(-1). From 3.070 to 2.620 eV, the indirect energy gap ( E-gap(indirect) ) was obtained. The energy E-U values of the Urbach grew from 0.210 eV to 0.659 eV as the concentration of (CeO2 + Yb2O3) increased. The range of values for refractive index (n) was 2.378 to 2.507. The generation of non-bridging oxygen (NBO) is improved by the addition of rare earths. When the concentration of [CeO2 + Yb2O3] in the glassy network is increased from 0 to 2.0 mol%, the mass-attenuation-coefficient (MAC) values at E = 0.015 MeV range from 7.746 to 13.676 cm(2).g(-1). Across the whole energy range, the sample coded as CY7 exhibits the best radiation protection effectiveness (RPE) values, demonstrating the strong influence of the [CeO2 + Yb2O3] molar fraction. The suggested CY0-CY7 glasses can be used in the fields of optical devices and radiation protection.
