Abstract
NiO/xFe(2)O(3) nanoparticles (NPs) with different Fe2O3 content of (x = 0.0, 0.3, 0.5 and 1) have been synthesized by microwave irradiation method. For more investigations, the solution of these NPs have been dropped on top of the glass substrate. The prepared films of the synthesized materials have been characterized by elemental analysis such as X-ray diffraction and Transmission electron microscope. An analysis of the phase composition and microstructure shows that Fe2O3 content has slightly influence on the crystal structure and morphology of NiO NPs, which reveals that the addition of Fe2O3 NPs has been incorporated into the NiO host lattice. A comparison between Fe2O3 and NiO NPs have been done using these analyses. The effect of Fe2O3 addition content in NiO lattice on the linear and nonlinear optical properties have been studied. The refractive index and the energy gap have been decreased by about 24% and 12.5% respectively with increasing Fe2O3 NPs contents. The improving optical conductivity of assembled films is verified due to the addition of Fe2O3 NPs. (C) 2017 Elsevier B.V. All rights reserved.
