Graphene doped tin oxide composites were prepared with SnCIZ·2HZ 0 and graphene oxide as rawmaterials with sol-gel method and then spincoated on the quartz glass to manufacture a new transparent conductivefilm. The composite film was characterized with X-ray diffraction(XRD)and scanning electron microscopy(SEM)analysis. XRD results show that the graphene oxide was successfully prepared with Hummers method. The graphenelayers and particulate SnOZ can be clearly observed in SEM photos. The transmittance and conductivity of the thinfilms were tested with ultraviolet visible spectrophotometer and Hall effect measurement. The results show that thetransmittivity of composite film in visible region is more than 90% and surface square resistance is 41 S2/口.Thegraphene/ SnOZ film exhibits a higher performance in transparence and conductivity than commercial FTO glass.
