Optical and structural properties of graphene oxide-noble metal bilayers

The practical use of graphene and graphene oxide beyond the research laboratories is strictly related to the fine tuning of new methodologies for processing and mass-production purposes. The photoreduction processing is an innovative route allowing exquisite control of the optoelectronic properties of graphene-like materials irradiated by coherent and incoherent light. We have investigated the effects induced by a mercury lamp on graphene/palladium bilayer; the change on the optical properties of the sample has been detected by using a surface plasmon resonance setup. The analysis, the perspectives and the preliminary results are shown thereafter.
