Impact of Yttrium Oxide on the Dielectric, Radiation-Shielding, and Physical Characteristics of Glasses Made of Lithium Bismuth Zinc Phosphate

This work has employed the melt-quenching technique to produce a series of P/Li zinc bismuth multi-component glasses doped with varying quantities of yttrium (Y₂O₃) oxide. The density of the resulting sample of phosphate glasses is increased when an appropriate amount of P₂O₅ is substituted with Y₂O₃. The structure of the glasses under investigation has been examined using FTIR (Fourier transform infrared) spectroscopy. The dielectric characteristics were investigated over a wide frequency range. An increase in the level of electrical stiffness throughout the glass network is indicated by the decrease in dielectric constant (ε′) with yttrium oxide insertion. Out of all the samples tested, glass sample Y-2.0 has the lowest dielectric constant and the maximum propagation velocity, making it the most appropriate for electronic packaging. Following the major band edge, the UV–Visible tests revealed that all samples exhibited good transparency and an excellent transmission range in the wavelength range of 350 to 900 nm. By adding more Y³⁺ ions to the glass structure, the refractive index (n), the extinction coefficient (k), the dielectric constant (ε₁, ε₂) and the optical conductivity were all improved. The energy gap values that are determined by graphing the extinction coefficient against photon energy show a drop from 3.982 to 3.346 eV. The effect of Y₂O₃ content on the shielding properties of this glass system was investigated theoretically by the Phy-X software program. All the measurements look at indicates that the Y3.0 glass specimen, which has the highest concentration of yttrium oxide (3.0% mole), has superior shielding properties.
