High-Resolution Imaging of the Electrochemical Interface by Operando Fluorescence Confocal Laser Scanning Microscopy.

ABSTRACT: Coupling electrochemistry with optical techniques gives in-depth insights into the interfacial processes in action. In that context, fluorescence confocal laser scanning microscopy (F-CLSM) enables an electrode surface characterization with spatial resolution in the lateral plane (xy) as well as in the axial direction (z), perpendicular to the electrode surface. However, like most optical techniques, fluorescence microscopy has intrinsic limitations, notably in terms of resolution and sensitivity, which are investigated in this contribution by conducting F-CLSM experiments with two disk electrodes of different sizes: a large microelectrode (LME, Ø = 250 μm) and a much smaller so-called ultramicroelectrode (UME, Ø = 18 μm). We demonstrated that the diffusion layers of both mic
