The paper reports on the fabrication and characterization of chemically and optically stable silver-based surface plasmon resonance (SPR) interfaces. The SPR interfaces are obtained by a radio frequency (rf) sputtering technique of titanium (Ti), silver (Ag), and indium tin oxide (ITO) targets in one run at ambient temperature. The best SPR signal in terms of shape and minimum intensity was observed for Ti (5 nm)/Ag (38 nm)/ITO (4 nm) interface. The role of ITO is primarily to protect the silver interface from chemical degradation. In addition, it provides an electrochemical addressable oxide-based interface.
