Abstract
Nonlinear and linear optical traits of vanadio-tellurite glasses in the form 50TeO(2)-(50-x)V2O5-xK(2)O (where x = 0-20 mol% (abbreviated as TVK glasses) were investigated. Besides, gamma ray shielding parameters were assessed utilizing the FLUKA simulation code. Results revealed that the molar refraction (R-molar) varied from 31.122 to 26.400 (cm(3)/mol), while molar polarizability (alpha(molar)) varied from 12.350 x 10(-24) to 10.476 x 10(-24) cm(3). The static dielectric constant (epsilon(static)) was within 10.298-6.789. The optical electronegativity (chi*) varied from 0.319 to 0.626 for TVK glasses. The nonlinear refractive index (n(Optical)) diminished from 5.996 x 10(-10) to 1.109 x 10(-10) (esu), while the nonlinear optical susceptibility (chi(3)) diminished from 5.107 x 10(-11) to 0.767 x 10(-11) (esu) with the V2O5/K2O substitution in the glasses. Gamma ray attenuation coefficients such as mu and mu/rho were calculated for six different photon energies in the range of 0.284-1.275 MeV. Both mu and mu/rho were used to evaluate the transmission factors (HVL and MFP) and the effective atomic number (Z(eff)). The Z(eff) parameter was useful to give a full understanding of the gamma ray shielding performance of the TVK glasses under V2O5/K2O substitution. Finally, the parameters of gamma ray shielding were compared with ordinary and commercial shielding materials.
