摘要
Abstract The rational design of functional plasmonic metasurfaces and metamaterials requires the development of high‐throughput characterization techniques compatible with operando conditions and capable of addressing single‐nanostructures. In their work, Wei et al. demonstrate the use of electrochemiluminescence microscopy to investigate the mechanism behind plasmon‐enhanced luminescence induced by gold nanostructures. The use of gold plasmonic arrays was exploited to achieve the rapid spectroscopic evaluation of all the individual nanostructures, and the correlation of the results with high‐ resolution electron microscopy analysis, guaranteeing a strict one‐to‐one correspondence. The authors were able to identify two different mechanisms for the enhancement of [Ru(bpy) 3 ] 2+ ‐tri‐n‐propylamine electrochemiluminescence mediated by single gold nanoparticles and by small plasmonic clusters. In the future, the proposed characterization could be used for the rapid and in situ spectroscopic analysis of more complex plasmonic nanostructures and metasurfaces.
