光与物质的相互作用是实现光能高效利用的重要手段。电化学电位控制方法可以调节分子与光场之间的耦合强度。在这项研究中，电化学表面增强拉曼散射测量已经进行了澄清在强耦合制度的详细分子行为。染料分子在强耦合区的拉曼和荧光强度为我们提供了分子与金属表面之间距离变化的信息。详细的光谱研究揭示了耦合强度的潜在依赖性的起源。本文的研究结果对于理解电化学控制的分子-光相互作用的光化学研究具有重要的参考价值。
The light–matter interaction is the crucial tool for the efficient light energy usage. Electrochemical potential control method can tune the coupling strength between the molecules and the light field. In this study, electrochemical surface‐enhanced Raman scattering measurements have been carried out to clarify the detailed molecular behavior in the strong coupling regime. The Raman and fluorescence intensities from dye molecules in the strong coupling regime provided us the information about the change in the distance between the molecules and the metal surface in angstrom level. The detailed investigation of spectra revealed the origin for the potential dependence on the coupling strength. The present insight obtained in the current study would be valuable to understand the electrochemically controlled molecule–light interaction for photochemistry research.
