| dc.description.abstract | © 2022In this work, novel nitrogen, fluorine co-doped carbon dots (N, F-CDs) have been synthesized by a hydrothermal method using melamine and 2, 4-difluorobenzoic acid as precursors. The obtained N, F-CDs exhibit excellent optical stability with high quantum yield. The N, F-CDs are highly selective to S2− detection by forming N, F-CDs@S2−, with a detection limit of 168 nM. The N, F-CDs@S2− were shown to be a highly selective Cd2+ detector by forming CdS, with a detection limit of 340 nM. The fluorescence quenching of N, F-CDs by S2− occurs via a static quenching mechanism and the fluorescence recovery was due to the high affinity of Cd2+ to S2−. The fluorescent sensor was used to determine Cd2+ and S2− in tap waters with satisfactory results. | |
