摘要: This study reports the occurrence of a special red-emitted anodic electrochemiluminescence (ECL) emission at+ 1.4 V (vs. Ag/AgCl) on a glass carbon electrode (GCE) after the addition of thioglycol (TG) to surface-unsaturated glutathione (GSH)-coated Au nanoclusters (NCs), with an emission peak at∼ 630 nm. Compared to the ECL at a potential of+ 1.8 V (vs. Ag/AgCl) and an emission peak at 580 nm (corresponding to fluorescence) for only GSH-coated Au NCs, this ECL emission not only exhibits a lower ECL potential but also shows a …
