Abstract

In this work, spectroscopic ellipsometry combined with transmittance measurements in a spectral range of 0.6 - 6.5eV (2.2μm – 193nm) have been used to determine the thickness and optical constants of carbon-palladium thin films. The C-Pd nanocomposite samples are synthesised by physical vapour deposition and chemical vapour deposition methods on to fused silica substrates. The C₆₀ fullerene and palladium acetate are used as the source materials. The effective complex dielectric functions [equation-see manuscript] of the particulate films are found to depend strongly on preparation technology and concentration of Pd nanoparticles embedded in the carbon matrix. Optical parameterisation with a Drude-Lorentz model of the dielectric functions has been applied to match the experimental data. Influence of chemical treatment and Pd nanoparticles on structural disorder and relevant optical and electronic properties of the C-Pd samples is analysed.
