N2 - In this study, the melt-quenching method has been used to obtain a set of Ca/Na lead borovanadate multi-component glasses doped with different contents of Y2O3. The effect of Y2O3 content on the structural properties of the amorphous glass system was investigated by the XRD (X-ray diffraction patterns), FTIR (Fourier transform infrared spectra), and DSC (Differential scanning calorimetric analysis), where the morphology analysis of the samples was performed by TEM. The physical and shielding properties of the investigated glass system were also determined. Using UV–VIS data the optical parameters including optical absorption coefficients, optical band gap for direct and indirect electronic transitions, Urbach's energy, refraction (n) and absorption (K) indices, optical dielectric constant's real (ε1) and imaginary (ε2) parts surface energy loss (SELF) and volume energy loss (VELF), optical and electrical conductivity and nonlinear properties were evaluated. In relation to the thickness used, the HVL values of the studied glasses were found to be better than those of concrete. The analysis of obtained results indicates the mixed alkali lead borovanadate multi-component oxide glass doped with high Y2O3 content is suitable as a protective coating material for various electrical and optoelectronic devices, including solar cell units, sheets, smartphones, computers, and TV screens. Also, the Y2O3 samples may be useful for shielding applications.
