Fe2O3/graphene, nanocomposite, graphene, hydrothermal method


A simple and straightforward approach was used to prepare Fe2O3/graphene nanocomposites with different temperature conditions. The nanocomposites were characterized by X-ray diffraction (XRD), Raman spectroscopy, field emission scanning microscopy (FE-SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS) and photoluminescence (PL). The results show that Fe2O3 nanoparticles with size in range of 60-100 nm are anchored on the surface and filled between the graphene nanosheets at hydrothermal reaction. The PL spectrum exhibits the emission peaks appeared at ~ 650 nm and ~ 720 nm.
