摘要：
Based on the principle of fluorescence quenching, by the interaction between S2- ions and the Ag atoms/ions on the surface of the core-shell Au@Ag NCs, we propose a simple label-free method for the detection of S2- ions with high selectivity and sensitivity by using fluorescent core-shell Au@Ag NCs in aqueous media.
