Abstract :
Metal nanodot arrays with the uniform diameter were fabricated utilizing nanoporous alumina mask with through-holes as an evaporation mask. Ag, Cu, and Au nanodot arrays were fabricated on indium tin oxide coated glass as a replica of the nanoporous alumina mask. The localized surface plasmon resonance (LSPR) properties of metal nanodot arrays were experimentally measured by the ultraviolet-visible spectroscopy. The dependency of LSPR wavelength on nanodot composition was examined.
