晶格磷(P)掺杂是调节石墨烯量子点（GQDs）荧光的有效方法。由于P有多种可能的氧化态，晶格P掺杂GQDs （P-GQDs）的合成仍然比较困难。在这里，我们报道了通过溶剂热处理卵磷脂，以高收率（71 wt%）绿色制备P-GQDs。所得的P-GQDs具有可控的发射波长（457-632 nm）和高量子产率（0.54-0.73），在荧光生物成像中具有潜在的应用前景。
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.
