In this study, magnetite(Fe3O4) nanoparticles with a size range of 40 nm were prepared by the modified controlled chemical co-pericipitation method. In the process, surfactant (sodium oleate) was used to attain ultrafine, nearly spherical and well-dispersed Fe3O4 nanoparticles. The size of nanoparticles were determined by particle size analyzer. The magnetite nanoparticles was characterized by X-ray powder diffraction (XRD) analysis, scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FTIR), UV-Visible absorption spectroscopy and vibrating sample magnetometer (VSM). The results showed that the Fe3O4 nanoparticles coated by sodium oleate had a more uniform Size Distribution, smaller size and better dispersion than the pure magnetite nanoparticles. On the other hand, The morphology of particles coated with sodium oleate was spherical and the aggregation effect is low. The results obtained from the (UV-Vis) absorption spectroscopy and Tauc relation  showed  the band gap of nanoparticles was about 2.5ev.
Keywords: magnetite nanoparticles, Optical Characterization of Fe3O4, co-precipitation method
