Structure and optical properties of nano Nix Cd1-x Fe2O4 doped with optical dyes

Abstract

NixCd1-xFe2O4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5) nanoferrite powder were synthesized using flash auto combustion method. The studied powder was characterized by X-ray diffraction (XRD), which was used to determine the structural properties. The effect of addition dyes (perylene dye and thiophene dye) on the optical properties of Nickel Cadmium ferrite has been investigated. The optical study UV-Visible is used to calculate the band gap energies. From Tauc's plot, it can be seen that the band gap energy of the samples is decreasing with increase in nickel content for both dyes, indicating the enhancement of the optical of ferrite.
