Abstract

Plasma polymer silver composite films were prepared by simultaneous or alternating plasma polymerization and metal evaporation. The optical properties in uv, vis and nir were studied as functions of the filling factor by means of transmission spectra. Intensity and width of the plasma resonance absorption depend strongly on the microstructure of the films. Different effective mrdium theories were discussed in connection with the microstructure. The effective dielectric functions and the transmission spectra were calculated. The best results were obtained with the extension of the Maxwell-Garnett theory for parallel oriented elliptic particles.
