The TiO2thin films were prepared using Ti(dpm)2(OPri)2and Ti(OPri)4(dpm = 2,2,6,6-tetramethylheptane-3,5-dione,Pri= isopropyl) as the precursors. The volatile compounds Fe[(C2H5)2NCS2]3and [(CH3)C]2S2were used to prepare doped TiO2films. The synthesis was done in vacuum or in the presence of Ar and O2. The pressure in the CVD chamber was varied between1.2×10−4 mbar and 0.1 mbar, with the system working either in the molecular beam or gas flow regime. Physical, chemical, and photocatalytic properties of the (Fe, S)-doped TiO2films were studied. Those TiO2:(Fe, S) films prepared from the Ti(OPri)4precursor show increased photocatalytic activities, very close to those of Degussa P25 powder in UV region.

The performance of nanocomposites semiconducting material used as a sensor is very much depending upon physical and chemical properties of the material. In this paper we address sensitivity of ZnSnO3thin film deposited by hydrothermal deposition in terms of its behavior towards humidity variations. The electrical, optical and structural properties of ZnSnO3thin film deposit at different volume of solvent (50 ml and 70 ml) grown by novel deposition of ZnSnO3hydrothermal with low temperature 95°C are also reviewed. The sensor performance of ZnSnO3thin film prepared at 50 ml volume show high sensitivity towards humidity. Using FESEM it was noted that the nanocube of ZnSnO3thin films growth on ZnO template with the size of nanocube is 100 to 140nm by varying the volume of the solvent.
