Thermochromic films of VO 2 were deposited by DC reactive magnetron sputtering on stainless steel substrate. Complex refractive indexes of VO 2 were determined by ellipsometric spectroscopy (0.35-16.5 μm) for different film thicknesses. Optical simulations were performed to model the spectral reflectance of the film/substrate system for a film thickness of 100 nm and 200 nm and to monitor the optical contrast of the thermochromic layers by comparing the spectral reflectance at 25 °C and 100 °C. The good agreement observed between experimental and theoretical spectra demonstrates the adequacy of the model for predicting the optical properties of the samples. © 2010 Elsevier B.V.

The optimization of the photocatalytic activity and hydrophilic conversion of TiO 2 is an active research area in the field of self-cleaning materials and energy storage/conversion. One major focus is the crystalline phase of TiO 2, known to be the most efficient of the anatase structures. Another issue is the decoration of TiO 2 with noble metals, which act as charge carrier traps for electrons. The latter hinders or reduces the electron-hole recombination rate and often leads to a more efficient photocatalytic activity. In this paper, we describe how an interlayer consisting of 3-4nm silver nanoparticles (Ag-NPs) promotes TiO 2 anatase crystallisation and has a positive effect on the photoinduced catalytic and hydrophylic properties of TiO 2 thin films. Ag-NPs and TiO 2 were deposited by magnetron sputtering in the same reactor in a two-step process: a) condensation of Ag-NPs produced in the gas phase thanks to a high-pressure discharge, and b) conventional TiO 2 magnetron deposition in oxide mode. Four temperatures from RT to 288°C were investigated and film thickness was 80nm. Particle size and film structure were determined by TEM, HRTEM and XRD. Photocatalytic activities of the samples were tracked by the evaluation of the surface hydrophilicity after UV illumination and 24. hours post-illumination, and by UV-induced palmitic acid degradation. © 2011.
