The localized Surface Plasmon Resonance Effect on metal nano-paticle thin film, widely used in biosensor and chemosensory, becomes a fast developing field. The way to obtain Spectrum based on Localized Surface Plasmon Resonance is the key technology to support, This paper introduces the principle of Localized Surface Plasmon Resonance, and a fabrication technique of nano-particle film is also presented. To finally obtain the Localized Surface Plasmon Resonance spectrum, one effective optical route is designed. At Last, the quantity of spectrum is shown, in which the effective coefficient such as absorbing wavelength peak value and so on can be obtained.
