    The supercritical fluid crystallization by pure and water modified supercritical carbon dioxide was used for the preparation of crystalline and pure nanostructured TiO2 thin films. Simultaneous, organic precursors used in the synthesis of solution to prepare thin films by sol-gel method were removed. The influence of temperature and the volume of solvent on the microstructure and the purity of TiO2 thin films was monitored by Raman spectroscopy and X-ray diffraction analysis. Anatase crystalline structure was achieved by the process with scCO2 modified by 30 wt. % water at temperature 150 °C.
