Abstract：Nanopores with rhombic shape were obtained by heavy ion irradiation and track etching single-crystal muscovite mica sheet of thickness 25 μm. The rhombic cross sectional shape has a major diameter of around 50 nm and a minor diameter of around 30 nm. The Au nanowires were fabricated by electrodeposition into the mica nanopores. The UV-Vis absorption spectra of Au nanowires show that the Au nanowires exhibite two surface plasma resonance (SPR) peaks due to the rhombic shape. The morphology and crystallinity of the Au nanowires were studied by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses.
