The Fluorescent Quenching Mechanism of N and S Co-Doped Graphene Quantum Dots with Fe(3+) and Hg(2+) Ions and Their Application as a Novel Fluorescent Sensor

The fluorescence intensity of N, S co-doped graphene quantum dots (N, S-GQDs) can be quenched by Fe(3+) and Hg(2+). Density functional theory (DFT) simulation and experimental studies indicate that the fluorescence quenching mechanisms for Fe(3+) and Hg(2+) detection are mainly attributed to the inn...
