High‐performance electrochemical plasmonic switching is realized on both single‐particle and ensemble levels by coating polyaniline on colloidal gold nanocrystals through surfactant‐assisted oxidative polymerization. Under small applied potentials, the core@shell nanostructures exhibit reversible plasmon shifts as large as 150 nm, a switching time of less than 10 ms, and a high switching stability.
