Dynamic responses at 300 °C of In2O3, 3 at% Zn-In2O3 and 5 at% Zn-In2O3 nanowires to 5 ppm of (a) acetone, (b) carbon monoxide, and (c) ethanol at optimal operating temperature, and bar graphs for different temperatures. Responses of In2O3, 3 at% Zn-In2O3 and 5 at% Zn-In2O3 nanowires to 5 ppm of (d) acetone, (e) carbon monoxide, and (f) ethanol at temperatures of 150–300 °C.
