Abstract:Surface plasmon resonance (SPR) sensors have attracted enormous attention due to their applications in various fields. A novel SPR-based sensor with ZnO and BaTiO3 metal oxide layers is designed for NH3 gas detection. Gold and silver are used as plasmonic materials and corresponding results are compared. The prism and plasmonic materials effects on sensor response are investigated. Moreover, thicknesses of gold and silver and metal oxide layers are optimized to obtain suitable performance parameters. sensor re… Show more
