Investigation of raman spectrum, structural, morphological, and optical features of Fe<sub>2</sub>O<sub>3</sub> and Fe<sub>2</sub>O<sub>3</sub>/reduced graphene oxide hybrid nanocomposites
Abstract
<jats:title>Abstract</jats:title><jats:p>The Hematite (Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>) nanoparticles and Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>-reduced graphene oxide (rGO) nanocomposite were successfully synthesized via co-precipitation method. The rGO was used as passivation layer to improve the optical properties of the Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>. X-ray diffraction, transmission electron microscopy, Raman, and Fourier transform-infrared spectroscopy were used to investigate the modification in the Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> structure in the presence of rGO. UV-visible absorption spectra were investigated, and the optical bandgap was determined. Using different relations like Moss, Rivandra, Anani, and others, the refractive index was calculated depending on the obtained optical bandgap. The refractive index values were compared with the data calculated from Duffy relation and good accordance was found between them. The optical bandgap and electronegativity were found to decrease by the addition of rGO in Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> matrix, while the refractive index was found to increase. Consequently, the Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>-rGO nanocomposites capacity to control optical properties makes it a perfect contender for a variety of applications.</jats:p>
