Near‐infrared electrochemiluminescence (ECL) of Au 18 nanoclusters revealed an extremely high quantum efficiency of 5.5 relative to that of Ru(bpy) 3 2+ , due to the exposed kernel facets, electrocatalytic loops and overlapped oxidation potentials of Au 18 and tri‐ n ‐propylamine (TPrA) as co‐reactant. ECL peak maxima at 832 and 850 nm were unambiguously identified as emissions from Au 18 0* , Au 18 1+* and Au 18 2+* by means of spooling ECL and photoluminescence spectroscopy.
