Synthesis, Characterization and Nonlinear Optical Property of Graphene-C60 Hybrid
The graphene-C60 hybrid has been synthesized and characterized. Its nonlinear optical property was investigated. Raman spectroscopy suggested a strong interaction between C60 and graphene. Based on UV and elemental analysis measurement, it is estimated that one C60 molecule is covalently attached for every ∼110 carbon atoms in graphene. The nonlinear optical performance of this hybrid material was studied using the Z-scan measurement and a much enhanced nonlinear optical performance was observed compared with that of the benchmark material-C60 and graphene. This may be partially attributed to the photoinduced electron transfer mechanism between graphene and C60.
