摘要

This research examined the effectiveness of adding tungsten oxide to antimony barium borate glass to protect humans from gamma radiation. Melt-quenching method was used to produce antimony barium borate glasses with different WO3 concentrations. The structural, physical, optical, mechanical and radiation shielding characteristics of manufactured glass were examined. The X-ray diffraction results indicated that the prepared glass samples are amorphous. Fourier transform infrared (FTIR) spectra illustrates that the presence of tungsten oxide in antimony barium borate glasses raises the cross-linkage network through the conversion of BO3 units into BO4 units, and more enhancement of the stability of glasses. The density of the antimony barium borate glass increased, with a decrease in molar volume as a concentration of WO3 increased. Both the packing density and the oxygen packing density increase as the ratio of WO3 increases, which makes glass compact. UV–Vis spectroscopy verified that the addition of WO3 improved the optical properties. As the concentration of WO3 increases, the absorption coefficient, extinction coefficient, and refractive index enhance. The indirect and direct bandgaps decrease while the Urbach band tails increase from 0.272 eV (WO = 0) to 0.345 eV (WO = 3) as WO3 concentration increases. Mechanical properties improved as WO3 doping concentration increased in antimony barium borate glass. The addition of WO3 to glass enhances its gamma-ray attenuation properties, where mass attenuation coefficient (MAC) decreases with increased photon energies and increases as the WO3 content increased. In the contract, the half-value layer (HVL) and tenth-value layer (TVL) have a maximized value at WO = 0 while achieving their minimum values at WO = 3. Furthermore, mean free path (MFP) reduces as WO3 concentration raises making a glass will be promising shielding material. These findings suggest that WO3-doped antimony barium borate glass is a promising candidate for radiation protection applications in medical, nuclear, and industrial fields.
