摘要：

The gold-coated multilayer graphene was obtained by simultaneous thermal reduction of gold ions and graphene oxide blend film under argon flow for an hour. The effects of thermal reduction temperatures (200 degrees C, 400 degrees C, and 500 degrees C) on the structural, optical, and electrical properties of gold-coated multilayer graphene were studied by using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), UV-vis spectroscopy, and four point probe measurement. The optical transmittance increased and the sheet resistance decreased with the thermal reduction temperature. The highest optical transmission of 66% and the lowest sheet resistance of 78.3 k Omega/sq were Obtained at thermal reduction temperature of 500 degrees C. (C) 2013 Elsevier B.V.
