Complex optical study of V2O5–P2O5–B2O3–GO glass systems by ultraviolet–visible spectroscopy

Abstract In the present work, complex optical parameters such as absorption, extinction coefficient, refractive index, optical conductivity, real dielectric constant and imaginary dielectric constant of V2O5–P2O5–B2O3–GO glass systems have been studied. The melt quenching method was adopted for the preparation of V2O5–P2O5–B2O3–GO glass systems. The conformation of glassy phase in sample was done through X-ray diffraction analysis. The optical parameters were analyzed using ultraviolet–visible spectroscopy. The dispersion of graphene oxide in V2O5–P2O5–B2O3–GO glass systems significantly affects the complex optical parameters. The extinction coefficient, real dielectric constant and imaginary dielectric constant gradually increase after 225–600 nm. Whereas, optical conductivity shows gradual increase around 225 nm.
