抄録

AuAg alloy nanowires in the geometrically anisotropic pores of the aluminum anodic oxidation films with a mean diameter of 10nm and depth of 10μm were successfully prepared by the electrodeposition of gold and silver under the bath voltage of 6V AC in a cyanide-free bath (Ag<sub>2</sub>SO<sub>4</sub>-HAuBr<sub>4</sub>-(NH<sub>4</sub>)<sub>2</sub>S<sub>2</sub>O<sub>3</sub>). The aspect ratio of the alloy nanowires was controlled by changing the electrodeposition time. The maximum position of absorption band due to the transverse surface plasmon resonances of AuAg alloy nanowires shifts to a longer wavelength with an increase of the composition of Au. The color and shading of the anodized aluminum deposited with alloy nanowires were simply tuned in a wide range.<br>
