We have changed the resonance energy of the graphene oxide molecular clusters by using the external electric field. From the graphene oxide resonance fluorescence we could study the polarization dynamics of graphene oxide under the electric field. It is found that the electric field makes the FWHM of fluorescence resonance peak tend to be saturated, and the temporal change of fluorescence resonance of the graphene oxide molecular clusters reflects the directional polarization and the deformation polarization generated in the graphene oxide due to the electric field.
