Preparation and characterization of silver substrates coated with antimony-doped SnO2 thin films for surface plasmon resonance studies.
This paper reports on the preparation of silver/antimony-doped tin oxide (Ag/SnO(2):Sb) hybrid interfaces using magnetron sputtering and their characterization. The influence of the Sn target composition (doping with 2 or 5% Sb) on the electrochemical and electrical characteristics of the hybrid interface was investigated using X-ray photoelectron spectroscopy (XPS), sheet resistance measurements, cyclic voltammetry, scanning tunneling microscopy (STM) and surface plasmon resonance (SPR). The best interface in terms of electrical conductivity and SPR signal is a hybrid interface with a 8.5 +/- 0.3 nm thick SnO(2):Sb layer obtained from a Sn target with 2% Sb deposited on 38 nm thick silver film. Different strategies to link functional groups onto the Ag/SnO(2):Sb interface are also presented.
