In this research, iron oxide nanostructures
have been successfully synthesized using the coprecipitation
method. The results of structural studies
using X-ray diffraction (XRD) analysis showed that the
synthesized samples have a simple cubic structure. The
lattice parameter of these synthesized nanostructures was
calculated with the aid of the Rietveld refinement
method. It was found that the lattice parameter is about
8.388 Å. Electron microscopy images (SEM) showed that
the samples have sheet likes shapes. From SEM images,
it was found that the synthesized nanosheets' thickness
was about 33 nm. The optical properties of the samples
were also studied using ultraviolet-visible spectroscopy.
These studies showed that the samples have a broad
absorption peak of about 350 nm. The samples were
irradiated with a beam with a wavelength of 205 nm to
measure the emission spectra. There were several
emission peaks observed in the emission spectra of
samples. The highest emission peaks were observed at
482nm and 527 nm, respectively. پرونده مقاله
