Abstract

The work presents structural and charge carrier dynamics of in-situ synthesized rGO/Fe3O4 nanocomposite (NC). TEM and FT-IR measurements were used to probe structure and results show the uniform dispersion of Fe3O4 nanoparticles onto rGO matrix in NC. The first systematic measurements on charge carrier dynamics of this NC material was investigated using ultrafast spectroscopy, which portray the occurrence of electron transfer from rGO LUMO to Fe3O4 HOMO and testify GO position as an electron donor in NC. These results demonstrate the potential optical/electrochemical sensing applications of the formed NC material.
