Abstract

Highly sensitive thick film ethanol gas sensors based on a nanocrystalline In2O3 were fabricated by painting methodon alumina substrates. The crystal structure of the In2O3 powder was characterised by XRD analysis. The microstructureof the films were characterised using FE-SEM. The experimental results of the ethanol gas sensing characteristics indicatedthat the undoped In2O3 oC for 2 hrs. wasas high as 32.73 at an operating temperature of 200oC to 1000 ppm ethanol gas in air.
