Abstract

The gas sensing properties of direct-patternable SnO2 thin films prepared by photochemical solution deposition were improved by an incorporation of graphene or Ag nanoparticles. The CO gas sensitivity of the SnO2 thin film was 3.65, but increased to 6.84 and 18.06 by the incorporation of graphene and Ag nanoparticles, respectively. Direct-patterning of graphene or Ag nanoparticles incorporated SnO2 thin films can be performed at the 40 μm scale pattern without a photoresist or an etching process.
