Nanostructured Ti-WO3 Thin Films for Gas Sensor Applications
In this work, undoped and Ti doped WO3 nanostructured films were prepared on the glass substrate using the electron beam evaporation method and the films microstructural, structural, chemical and gas sensor properties were studied. Undoped WO3 films show the presence of nanoflakes and the surface appears homogenous and smooth. The nanoflakes are turned into nanorings after doping the Ti into WO3. The target gases were tested at room temperature (30oC) with the same concentration. The Ti-WO3 sensor possesses excellent selectivity towards hydrogen gas compared to other gases.
