Description
Summary:A silver-gold compound metal island film prepared by using a two-step evaporation method is demonstrated for the first time. Silver and gold islands have been completely alloyed by heating the film at 300 degree C. The resonance wavelength of the compound metal island film exists between those of pure silver and pure gold island films. It is shown that the resonance wavelength can easily be controlled by selection of the mixture ratio of silver and gold.
