| Popis: | The emerging field of organic/inorganic nanocomposites has become the focus of considerable research in recent years. In particular, graphene coated with iron oxide nanostructures are widely required for various applications. In this work, we report the preparation of graphene oxide/magnetite GO/Fe3O4 nanocomposite via a simple hydrothermal method. Our experimental results obtained by transmission electron microscopy (TEM) reveal that well defined Fe3O4 nanorods (NRs), about 8-11 nm in diameter and 50-60 nm in length, were uniformly anchored on graphene oxide nanosheets. X-ray diffraction (XRD) confirms the successful assembly of Fe3O4 on to GO nanosheets. Thermo gravimetric analysis results(TGA) show a good thermal stability for the nanocomposite. Raman laser studies carried out at various laser powers and acquisition times show that all the samples undergo changes in intensities and peak positions which reflect the modification of the electronic structure and electron-phonon interactions. |
