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.
