Abstract
Pure ZnO and 3 wt.% Ga-doped ZnO nanopowders were synthesized by a simple sol-gel technique, dried in supercritical conditions and annealed at 400 °C. The effect of Ga-doping on the morphological and structural properties were evaluated by TEM and XRD. CO sensing properties of the synthesized samples were investigated, demonstrating that Ga-doping has a strong impact on CO response. The effect of UV light on electrical and sensing properties of GZO-based sensor response was also evaluated.
