“…Our waveguide SPR results are also consistent with other reported SPR studies carried out using the Kretschmann configuration to measure the resonant angle. 7,10,15,16,30 From these studies a common consensus model emerges. Between 0.5 V and 1.13 V on the anodic scan the voltammetry of the polycrystalline electrode is essentially featureless with only double layer charging and, for bisulfate/sulfate anion some evidence for specific adsorption, at least for single crystal electrodes.…”

“…More recently Iwasaki et al 10 have used the Kretschmann configuration to study (111) oriented gold films and electrode reactions at gold surfaces 11,12 and it has been used to study redox transformations in electroactive polymers at electrode surfaces. 13,14 The Kretschmann configuration has the disadvantage that it is limited to the study of thin evaporated metal films; to overcome this problem Tadjeddine et al 15,16 have used the Otto configuration which allows single crystal metal surfaces to be used, albeit at the expense of additional experimental difficulties. All of these studies have demonstrated that the SPR technique is very sensitive to changes occurring at the electrode surface.…”

We describe the fabrication and characterisation of gold-coated graded index channel waveguide sensors designed for simultaneous electrochemical and surface plasmon resonance studies. The active sensing electrode area is a thin gold film between 0.5 and 5 mm in length and 200 mm wide deposited on top of a 3 mm wide waveguide which forms one arm of a Y-junction while the other arm of the Y-junction serves as a reference. Using these devices we have measured simultaneously the changes in transmittance through the device whilst carrying out cyclic voltammetry in either sulfuric or perchloric acid solution or during the deposition of an UPD layer of copper at the gold surface. In all cases we obtain stable and reproducible results which demonstrate the very high sensitivity of the devices to sub-monolayer changes occurring at the gold electrode surface. The response of these integrated optoelectrochemical devices is discussed in terms of a numerical model for the propagation of light within the waveguide structure.

The processes of oxide film formation and ion adsorption on gold electrodes were monitored by the simultaneous measurement of electrochemical potential scanning voltammetry and surface plasmon resonance (SPR) condition. The time differential of the SPR incident angle was used for the analysis of the surface reactions of the gold electrode. Each stage of oxide film formation on the sputtered gold electrodes and anion adsorption/ desorption was clearly detected by this method and directly correlated to the current. SPR is sensitive to the surface adsorbate while the electrode current reflects the overall electrochemical process. This difference was used to separate adsorption from the diffusion process under different hydrodynamic conditions.
