Reversible Electrochemical Tuning of Optical Property of Single Au Nano-bridged Structure via Electrochemical under Potential Deposition

Abstract

Here we report the optical property control of Au nano-bridged structures by the single-atom metal layer deposition onto the surface. The deposition and dissolution of the Cu atom layer were performed by the electrochemical under potential deposition method. Through the control of the reversible electrochemical deposition and dissolution process, the reproducible photoswitching behavior was observed.
