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

The Fluorescent Quenching Mechanism of N and S Co-Doped Graphene Quantum Dots with Fe<sup>3+</sup> and Hg<sup>2+</sup> 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<sup>3+</sup> and Hg<sup>2+</sup>. Density functional theory (DFT) simulation and experimental studies indicate that the fluorescence quenching mechanisms for Fe<sup>3+<...
