Abstract

• Nickel substituted bismuth ferrites(BiFe1-xNixO3; x = 0.1, 0.2, 0.3, 0.4 and 0.5) materials was synthesized using combustion technique. The synthesized material powders were sintered at 900C for 4 hours. X-ray diffraction technique (XRD)was used to confirm the nano-crystallite structure and phase formation. The particle size was estimated by the full width half maximum (FWHM) of the strongest X-ray diffraction (XRD) peak. The characterization of these materials was analyzed by Fourier Transform Infrared spectroscopy (FTIR). The optical band gap of these materials was also investigated from the transmittance spectrum. The energy band gap Egis in the range of 4.7 eV to 5.1 eV for prepared samples.
