We report the unusual generation of near-infrared (near-IR) electrochemiluminescence (ECL) from water-soluble Au nanoclusters (NCs), of which the photoluminescence is primarily within the visible wavelength region. The near-IR ECL is ascribed to the Au(0)–glutathione motif in the Au NCs stabilized by glutathione in water.
