dc.description.abstractSwitchable surface redox chemistry is demonstrated in gold@iron/iron oxide core–shell nanoparticles with ambient oxidation and plasmon-mediated reduction to modulate the oxidation state of shell layers. The iron shell can be oxidized to iron oxide through ambient oxidation, leading to an enhance- ment and red-shift of the gold surface plasmon resonance (SPR). This enhanced gold SPR can drive reduction of the iron oxide shell under broadband illumination to reversibly blue- shift and significantly dampen gold SPR absorption. The observed phenomena provide a unique mechanism for con- trolling the plasmonic properties and surface chemistry of small metal nanoparticles.en_US
