Al2O3 modified ZnO composite thick film for ethanol gas sensing

Abstract

The Al2O3 modified ZnO nanostructure with 1:9 ratio was synthesized at 500°C using solid-state reaction technique. The prepared nanostructure material was characterized with XRD and FE-SEM technique. XRD indicate the formation of wurtzite phase of ZnO. FE-SEM confirms the formation of hexagonal shaped rod like morphology. The sensing characteristic of the material was tested using ethanol gas.
