英文摘要	Gold colloid was prepared via electrochemical method. Nanostructured gold thin-films were deposited on glass by using self-assembled technique. UV-visible spectra and fluorescence emission spectra were measured at room temperature. The absorption spectrum features show two peaks and the longer wavelength one at 610 nm corresponds to linear aggregated gold nanochains. The fluorescence emission peaks at about 375 nm and 700 rim are due to the local field enhancement via coupling to the transverse and longitudinal surface plasmon resonance from gold nanochains. Both the intensity and number of the fluorescence emission peaks increase with increasing excited light and the layers number. It is indicated that the nanostructured gold thin-films formed a disordered particles system. Further more, multiple scattering takes place in these self-organized random micro-cavities.
