ABSTRACT: The Spinel Ferrite Co1-xCexFe2O4 with different compositions (x = 0.0, 0.33, 0.66, 1.0) were prepared by solid state reaction method. FTIR (Fourier Transform Infrared Spectroscopy), SEM (Scanning Electron Microscopy) and UV Spectroscopy (Ultraviolet) have been used to study the phase conformation, morphology and structural properties of all synthesized compositions respectively. Lattice constant was observed to be decreased as smaller ionic radii Co2+ (0.74 Å) replaced the higher ionic radii Ce2+ (1.14 Å). FTIR confirm the formation of cubic spinel ferrites by stretching vibration of metal oxide ion mechanism. SEM shows the surface morphology and grain size for synthesized cubic spinel ferrites in the range of 1.25 - 2.65 μm. Opti-cal band gap energy was determined in the range of 1.4575 - 1.425 eV for x = 0.0 to 1.0 nano-ferrites, respectively. This range of band gap energy indicates that the synthesized ferrites have potential applications in electrical devices.
