title = "Green preparation of lattice phosphorus doped graphene quantum dots with tunable emission wavelength for bio-imaging",
abstract = "Lattice phosphorus (P) doping has been demonstrated as an effective method for tuning the fluorescence of graphene quantum dots (GQDs). Due to the many possible oxidation states of P, lattice P-doped GQDs (P-GQDs) are still difficult to synthesize. Here, we report the green preparation of P-GQDs via solvothermal treatment of lecithin with high yield (71 wt%). The resulting P-GQDs show controllable emission wavelength (457–632 nm) and high quantum yield (0.54–0.73), and have demonstrated potential for applications in fluorescent bio-imaging.",
