Abstract

Metal islands films (MIFs) of Ag on glass substrates were fabricated by the e-beam evaporation process. The dependence of the surface plasmon (SP) absorption wavelength on the deposition mass thickness and substrate temperature was quantified. The structural and optical characterization of the MIFs, done by spectrometry, grazing incidence small angle X-ray scattering (GISAXS) and atomic force microscopy (AFM) evidences that the evolution of SP characteristics with the fabrication parameters: red-shift of the absorption peaks with the increase of deposition thickness accompanied by peak widening and the blue-shift of peaks with the increase of deposition temperature followed by the peak narrowing. These findings were explained by the differences in the concentration, shape and size of the obtained silver islands.
