Graphene oxide is an efficient fluorescence quencher for various organic dyes. Herein the fluorescence quenching of graphene oxide has been carried out on a naphthalimide dye as a fluorescent probe model. The interaction between naphthalimide dye and graphene oxide was studied by UV-Vis and fluorescence spectroscopic techniques. The results indicated that graphene is a very efficient quencher for naphthalimide molecule. The Stern-Volmer analysis revealed that the remarkable quenching of graphene was based on a combined static and dynamic quenching mechanism and went through an energy transfer process.
