| Abstract: | A glass system of barium borate (BaO–B2O3) with varying concentrations of vanadium pentoxide (V2O5), ranging from 2.5 mol.% to 7.5 mol.% at the expense of BaO, was examined as transparent radiation shielding material. The experimental glass density (Dexp) was utilized to predict the elastic and radiation shielding parameters. The density of the barium borate was 3.97 g/cm3, decreasing to 3.62 g/cm3 when V2O5 substituted 7.5% of BaO, related to the formation of non-bridging oxygens (NBOs). The incorporation of V2O5 into the glass network enhanced the Young's modulus (E) and shear modulus (G), which increased from 78.500 GPa (the base sample) to 79.412 GPa (7.5 mol.% of V2O5) and from 32.580 GPa to 33.101 GPa, respectively. Moreover, V2O5 influences the optical transmittance of the barium borate glasses. The cutoff wavelength was redshifted from 240 nm to 562 nm with the introduction of 7.5 mol.% of V2O5. Furthermore, the optical transition energy (Eg) decreased from 2.98 eV to 1.37 eV, while the static refractive index (no) was calculated from the Eg value, increasing from 2.402 to 3.076. The mass attenuation coefficient (MAC) of barium borate glass was 1570.8228 cm2/g at 0.002 MeV, which dropped to 1429.5712 cm2/g after substituting BaO with 7.5 mol.% of V2O5. Moreover, at an energy of 0.2 MeV, the MAC for the base and 7.5 mol.% V2O5 were 0.2843 cm2/g and 0.2553 cm2/g, respectively. All glass samples with a thickness of 0.75 cm can efficiently attenuate the high radiation energy of 0.2 MeV to its half-value. [ABSTRACT FROM AUTHOR] |
