ABSTRACT：
Ag nanorods have been successfully fabricated by a mixed-gases sputtering without any extra catalysts and Ag nanorods were arrayed on the film surface. The Ag buffer layer existed between the bottom of Ag nanorods and Si substrate. Ag nanorods located on the metallic silver particles after the thermal decomposition of the silver oxide. The formation of silver oxide resulted from the input of oxygen during the sputtering. The subsequent growth for Ag nanorods started from the single metal silver grain that originated from the decomposition through thermal reduction. This mechanism of oxidation reduction growth (MORG) used no catalysts and improved interface effect.
