The spectral properties and structures of the films have been analysed by UV–Vis–NIR spectrophotometer and transmission electron microscope (TEM) respectively. The optical constants of the films were calculated by means of the Hadley equation based on the transmittance spectra and reflectance spectra. The variation of the surface plasmon resonance (SPR) peaks with filling factor was investigated. The results show that in certain extent the FWHF(full–width at half maximum) and intensity of SPR peaks increase with increasing filling factor, and SPR peaks redshifts with increasing filling factor.
