Summary
TiO2 and W/TiO2 thin films have been prepared by a chemically modified sol-gel technique. Oxide-polymer thin films were deposited by dip-coating. Annealing at 500°C results in nanosized structurally stable oxides films. The dopant concentration led to a final W/Ti ratio of 1/33, 5/33, 10/33. The morphological and structural characteristics of thin films were studied through microraman, GIXRD, SEM and TEM. A microstructural comparison between pure and doped TiO2 layers is reported. Ethanol and methanol sensing properties are tested. TiO2 and W/TiO2 structural features and sensing characteristics are compared.
