The Effect of Change of Particle Nano Size and Concentration of Fe3O4 and Ni2O3 on Optical and Magnetic Properties Using XRD, SEM and UV-VIS

Abstract

The aim of this work is to find the optical parameters like absorption coefficient and energy gap and to find the electric permittivity and magnetic permeability for (Fe3O4 and Ni2O3) Nanomaterial thin films that were deposited on ITO glass substrate, ten samples were prepared by sol-gel method with deferent concentrations (55.25, 78.7, 90.9 144.9 and 263.15) mg/cm2 for each nanomaterial. The Nano crystal size of the deposited was found by the XRD technique. The UV-VIS spectrum was used to find absorption coefficient, energy gap refractive index and electric permittivity. The magnetic permeability was found by using the relation between refractive index and electric permittivity beside magnetic permeability. For Fe3O4 the electric permittivity and magnetic permeability were shown to increase when the concentration of Nano crystal decreases. However for Ni2O3 the electric permittivity and magnetic permeability increases upon increasing the molecular concentration. For all samples the absorption coefficient decreases upon increasing the concentration, while the energy gap increases with concentration. The Fe and Ni properties when they are mixed together is also needed. The results obtained can be applied for electric generation and magnetic resonance imaging.
