This study investigates the effect of substituting tungsten(vi) oxide/gadolinium(iii) fluoride in tellurite glasses whose densities varies from 5.0879 to 5.3246 g/cm3 on gamma-ray absorption properties. A range of fundamental absorption parameters, including attenuation coefficients, half-value layer thicknesses, effective atom and electron numbers, effective conductivity, exposure, and energy absorption buildup factors, were studied for five different glass samples with varying substitution ratios. The ratio of tungsten(vi) oxide to gadolinium(iii) fluoride varied between 0 and 20 mol%, as well as the TeO2 ratio in the composition was maintained between 90 and 80 mol%. The sample with the composition of 80–20 mol% TeO2/WO3, which attained the maximum density value with 20 mol% WO3 addition, showed the highest gamma-absorption capabilities based on the obtained findings in the range of 0.015–15 MeV. In consideration of the mechanical and physical properties of WO3 in tellurite glasses, it can be concluded that WO3 incorporation is a crucial monotonic process that may be utilized to further improve the properties of glass shields.

We report the mechanical properties, elastic moduli, and gamma ray attenuation properties of some TeO2–WO3–GdF3 glasses. Using the chemical composition of the selected glasses, the dissociation energy per unit volume (G t ) and the packing density (V t ) were calculated. Using the G t and V t values, Young’s, Shear, Bulk, Longitudinal Modulus, and Poisson’s ratio of the glasses are calculated. Next several fundamental gamma ray attenuation properties such as linear and mass attenuation coefficients, half value layer, mean free path, effective atomic number, effective electron density, effective conductivity, exposure, and energy absorption buildup factors are calculated in 0.015–15 MeV energy range. As a consequence of WO3–GdF3 substitution, the glass densities are observed in different values. The overall gamma ray attenuation properties are found to be enhanced through WO3 addition. Moreover, the increasing WO3 incorporation into glass configuration decreases the overall elastic moduli of glasses. It can be concluded that increasing WO3 may be a useful tool for enhancing the gamma ray attenuation qualities and decreasing the elastic moduli of TeO2–WO3–GdF3 in situations where a material with versatile mechanical properties is required.

We report the symmetry of mechanical and gamma-ray attenuation properties for some
tellurite glasses through elastic moduli, mechanical, and transmission properties as a function
of varied WO3 amount in glass configuration. Four glass samples, along with different molar
compositions as well as WO3/GdF3 substitution ratios, are investigated. Transmission properties
using several essential parameters, such as attenuation coefficients, half-value layers, effective atomic
numbers, effective conductivity, and buildup factors, are calculated in the 0.015–15 MeV energy
range. Moreover, elastic moduli and Poisson’s ratios ( ) of the studied glass are calculated using the
Makishima–Mackenzie model. The M4 sample with the highest WO3 addition is found with superior
photon attenuation properties among the glasses investigated. Poisson’s ratio ( ) is increased, while
all elastic moduli are decreased. Young’s modulus is reported as 62.23 GPa and 36.45.37 GPa at
the highest and lowest WO3 mol%, respectively. It can be concluded that WO3 is a functional and
monotonic tool in ternary-tellurite glasses for multiple modifications and enhancement purposes
on gamma-ray attenuation, elastic moduli, and mechanical properties. It can also be concluded
that increasing the WO3 amount in tellurite glasses may be considered a tool in terms of providing
symmetry for mechanical and gamma-ray attenuation properties.
