Characterisation of vanadia doped titania nano thin film using acoustical and other techniques

Johnson Irudayaraj

The functional characteristics of a nano thin film/coating depends critically upon its interface characteristics and adhesion to the substrate. The acoustical and mechanical properties of nano thin films and multilayer assemblies are important both for technological applications of these materials and for basic scientific studies of their physical behavior. This report presents the characterisation on the synthesised vanadia (4 mol.%) doped titania (TiO2) nano films by acoustical and other techniques. The acoustical, optical and structural characteristics of TiO2 films on Si (100) and quartz-glass substrates have been investigated. The surface acoustic wave properties of Vanadia doped TiO2 films were presented. Acoustical characterisation has been done with High frequency ultrasound sensors. They have been well correlated with the X-Ray diffraction, SEM, and UV- visible spectroscopy studies.
