A closer inspection of the structural, mechanical, optical and radiation shielding properties of GeO₂-doped magnesium-telluroborate glasses

Abstract

GeO₂-doped magnesium-telluroborate transparent glasses were synthesized in the current investigation using the traditional melt-quench procedure. XRD and FT-IR were used to examine the glasses’ structural properties. Following the measurement of the density, various physical parameters (including oxygen molar volume, oxygen packing density, etc.) were estimated and examined. From the FTIR results, one can deduce that clear structural alterations are seen which support the presence and conversion of BO₃ and BO₄ units. This is a result of the glass network forming more GeO₄, TeO₄, and BO₄ units, which means that decreased NBO is forming, and more stiff networks are forming as a result. The increase in the overall stretching force constant of the glasses may also have an impact on the elastic moduli. The optical parameters were studied as optical energy band gap, Urbach energy and refractive index of the fabricated glass. According to the HVL data, the current glasses have a significant ability to lessen the intensity of gamma rays with lower energy. The glass with a small amount of GeO₂ has a high HVL, whereas the glass with a higher amount of GeO₂ has a lower HVL, as shown by the HVL data. The G5 glass demonstrated its superiority as a shielding glass over the other glass samples (G1–G4).
