The dependence of the crystalline quality and optical property of the SnO2 film on the sputtering power was systematically studied. High quality SnO2 film was grown on RGC film at an optimum sputtering power of 150 W. The optical properties of the composite film can be tailored by adjusting the thickness of the SnO2 film. The SnO2/RGC composite film exhibited high visible transparency and excellent UVBshielding capacity, which can be used for protection against short-wave radiation.展开更多
