Published in 2017 at "Advanced materials"

DOI: 10.1002/adma.201604862

Abstract: 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… read more here.
