title: Preparation and optical properties of Au/Teflon nanocomposites.
abstract: Using thermal deposition technique, we have prepared Au/Teflon thin films on glass substrates. To control the film microstructure, both TEM and AFM characterization have been carried out. The visible optical transmission spectra have been measured in-situ. The peak positions and linewidths in the spectra have been identified in terms of the gold nanoparticle shape, size, and arrangement. The results obtained provide evidence for formation of both sphere-like and cylinder-like gold nanoparticles in the films. The fraction of each kind of the particles depends on whether the plasma treatment has been used. The treatment is shown to enhance the fraction of the cylinder-like particles.
