Abstract
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.
