Complex optical study of V₂O₅–P₂O₅–B₂O₃–Dy₂O₃ glass systems

Abstract

In this study, complex optical parameters such as absorption, extinction coefficient, refractive index, optical conductivity and real and imaginary dielectric constants of V2O5–P2O5–B2O3–Dy2O3 glass systems were studied. The conformation of the glassy phase in a sample was accomplished by X-ray diffraction analysis, and the material's optical parameters were analyzed using ultraviolet–visible spectroscopy. The extinction coefficient and real and imaginary dielectric constants were found to linearly increase above 225 nm, and the optical conductivity in V2O5–P2O5–B2O3–Dy2O3 glass systems was found to gradually increase near 225 nm.
