▎ 摘　　要

We demonstrate that gold nanorod arrays support LSPR modes which coincide with Frankel excitons in an organic J-aggregate complex forming plexciton hybrid states when tuned to within the strong coupling limit. The addition of graphene oxide modifies the strong coupling resonance conditions and Rabi frequency. This demonstrates that the formation of exciton-plasmon plexciton states in the strong coupling limit can be modified and potentially controlled through the introduction of graphene oxide which can have implications for energy harvesting or biosensor device design.
