Abstract
Eco-friendly metal titanates, which are abundant in nature, are widely used in our day-to-life in a variety of areas. This work is focused on the optical properties of FeTiO3 (FT) nanoparticles prepared by acid extraction method from ilmenite sand. The prepared FeTiO3 nanoparticles were analyzed by ultraviolet (UV) spectroscopy. Various linear optical parameters such as refractive index, extinction coefficient, absorption coefficient, real and imaginary parts of dielectric constant, loss tangent, optical conductivity, electron energy loss, and dielectric relaxation time were calculated in 1.5–6 eV energy range and discussed as a function of photon energy. The calculated values of the real part of complex permittivity and volume energy loss were higher than those of the imaginary part of complex permittivity and surface energy loss, respectively. The discussed results showed that the prepared FeTiO3 nanoparticles are suitable for the photocatalytic activity and optoelectronic device applications due to their hybridization orbital.
