عنوان انگلیسی Investigation of optical and structural properties of iron oxide nanostructures synthesized by co-precipitation method
چکیده انگلیسی مقاله In this research, iron oxide nanostructureshave been successfully synthesized using the coprecipitationmethod. The results of structural studiesusing X-ray diffraction (XRD) analysis showed that thesynthesized samples have a simple cubic structure. Thelattice parameter of these synthesized nanostructures wascalculated with the aid of the Rietveld refinementmethod. It was found that the lattice parameter is about8.388 Å. Electron microscopy images (SEM) showed thatthe samples have sheet likes shapes. From SEM images,it was found that the synthesized nanosheets' thicknesswas about 33 nm. The optical properties of the sampleswere also studied using ultraviolet-visible spectroscopy.These studies showed that the samples have a broadabsorption peak of about 350 nm. The samples wereirradiated with a beam with a wavelength of 205 nm tomeasure the emission spectra. There were severalemission peaks observed in the emission spectra ofsamples. The highest emission peaks were observed at482nm and 527 nm, respectively.
