Abstract
In this paper we discussed the optical and radiation shielding properties are strongly dependent on the physical parameter viz; (i) interionic interaction parameter, A(n0), (ii) coordination number, CN, (iii) single bond strength (BM-O) and (iv) optical basicity, Λ(n0) of glasses (95-x) TeO2– 5Ta2O5 -xBi2O3) where x = 5, 10, 15, and 20 in mol %. Furthermore, the various optical parameters viz; linear refractive index, optical absorption coefficient, optical energy gap, Urbach energy, density, oxygen molar volume, nonlinear refractive index, molar refraction, oxygen packing density, reflection loss, molar electronic polarizability of fabricated glasses were estimated. The shielding parameters viz; mass attenuation coefficient, linear attenuation coefficient, half value layer, mean free path, tenth value layer, effective electron number, effective atomic number, atomic and electronic cross sections have been calculated of fabricated glass against a wide range of ionizing energy ranging from 0.015 to 15 MeV. Results showed that increasing the concentration of Bi2O5 from 5 to 20% led to an increase in the linear attenuation coefficient (LAC). Compared with commercially available standards and reported some tellurite glasses to contain Bi2O3 in the literature, the investigated material showed superior performance at energies ranging between 800 keV and 10 MeV. Radiation protection efficiency (PRE) of 70TeO2–5Ta2O5–20Bi2O3 glass varied from 99.9 to 83.9% at low energy from 15 to 200 KeV. Therefore, this glass has a high density, refractive index, and a superior capability of radiation shielding materials at low energy.
