Structural, optical and gas sensing properties of Ag-SnO2 plasmonic nanocomposite thin films
Source abstract
Abstract
Abstract Nanocomposite thin films of Ag-SnO 2 were synthesized by simple thermal evaporation based vapor deposition method combined with thermal annealing. The morphological, structural, optical and plasmonic properties of the nanocomposite thin films were studied by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and UV–visible absorption spectroscopy. UV–visible absorption studies revealed surface plasmon resonance (SPR) peak at 421 nm confirming the presence of Ag nanoparticles in the nanocomposites. The annealed Ag-SnO 2 nanocomposites exhibited enhanced CO gas sensing properties including high sensitivity, fast response-recovery and good selectivity towards CO gas. A tentative mechanism for the enhanced CO gas sensing properties of Ag-SnO 2 nanocomposites is proposed.
