摘要：

In this article, high dense glasses based heavy metal former and modifier have been synthesized. The glass system with composition formula of (60-x)TeO2-10G-O-2-20ZnO-10BaO - xBi(2)O(3) (where x = 2.5, 5, 7.5, and 10 mol. %). The glasses have been produced using the usual melt, quenching, and annealing process. Many physical features were investigated. To confirm the amorphous nature of theses glasses, we examined the samples with X-ray diffraction in the range of between 10 degrees and 80 degrees. Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) transmission spectrum for the current glass samples within the range of 400e1500 cm(-1) has been recorded to study the behavior of the obtained glasses that is mixed between tellurium and germanium glass phase. To study the transparency and cut-off wavelength and other optical properties, Ultraviolet-Visible spectrometer (UV-Vis) was utilized between 200 and 800 nm. Radiation shielding ability of the (60-x) TeO2-10G-O-2-20ZnO-10BaO-xBi(2)O(3) glasses was examined. Monte Carlo simulation method was applied to estimate the shielding parameters for gamma photons with various energies varied in rang from 0.015 to 15 MeV. (c) 2020 Elsevier B.V.
