Based on the extensive research on graphene oxide photovoltaic materials, the optical properties of monolayer graphene oxide have been improved and manipulated.In this paper, the transmission intensities and imaging changes of monolayer graphene oxide under external electric field are studied. Transmission imaging reflects the monolayer oxidation The anisotropy, transmission and fluorescence intensity changes of graphene optical properties reflect the reversible controllability of the optical properties of monolayer graphene oxide under the action of an electric field.By using the polarization effect of polar oxygen-containing functional groups in graphene oxide under the electric field , Changing the electronic local density distribution of the sp3 carbon to change the optical properties of the monolayer graphene oxide and exhibiting the directional polarization of the oxygen functional group by the electric field.
