Transmission Electron Microscopy Studies of Nanostructured TiO2 Films on Various Substrates

A chemical vapour deposition (CVD) synthetic route to nanocrystalline titanium dioxide has been carefully investigated on different substrates. CVD was performed at low temperatures of 320 0C onto KCl crystal, Al foil, KBr pellet and freshly sliced mica. The influence of substrate material on formation of films were studied in order to connect their the improved intercalation properties. The structural properties and morphology of films were determined with transmit ion electron microscopy (TEM) and X-ray difrraction (XRD). With help of TEM the crystalline structure with formation of TiO2 (tetragonal system) in all films is observed. The average grain radius <R>, obtained by (TEM) was compared for different substrates.
