Active plasmonic nanostructures have garnered considerable interest in physics, chemistry, and material science due to the dynamically switchable capability of plasmonic responses. Here, the first electrically dynamic control of magnetic plasmon resonance (MPR) through structure transformation by selective deposition of lithium on a metal–insulator–metal (MIM) structure is reported. Distinct optical switching between MPR and surface plasmon polariton (SPP) excitations can be enabled by applying a proper electrical current to the electrochemical cell. Furthermore, the structure transformation through lithium metal deposition indicates the reconfigurable MPR excitation in a full cycling of the charging and discharging process. The results may shed light on electrically compatible self‐powered active plasmonics as well as nondestructive optical sensing for electrochemical evolution.

基于选择性锂沉积的磁等离子体共振电动态切换。

由于等离子体响应的动态可切换能力，有源等离子体纳米结构已在物理学，化学和材料科学领域引起了相当大的兴趣。在这里，据报道，通过在金属-绝缘体-金属（MIM）结构上选择性沉积锂，通过结构转变对磁等离子体激元共振（MPR）进行了首次电动力学控制。通过在电化学电池上施加适当的电流，可以在MPR和表面等离子体激元（SPP）激发之间进行明显的光学切换。此外，通过锂金属沉积的结构转变表明在充放电过程的完整循环中可重构的MPR激发。
