Pt/TiO2 thin film nanocomposites have been prepared using a process of
bi-combinant target pulse laser deposition. Pt nanoparticles have been
produced, possibly in the deposition process through rapid surface
diffusion. The nanocomposite films can be created with the anatase form of
TiO2 being the dominant crystal structure. The Pt nanoparticles are about
30 nm in size and homogeneously distributed. These thin films exhit an
optical band gap <2.3eV and a photoluminescence emission between 680 - 800 nm.
