Zusammenfassung:Carbon dots (CDs) as a novel type of nanomaterials have attracted significant attention in various scientific communities because of their excellent fluorescence. Herein, green fluorescent CDs (G‐CDs) were obtained using one‐pot hydrothermal treatment of Lonicera maackii fruit and exhibited excellent fluorescence characteristic and good bio‐compatibility. The as‐synthesized G‐CDs displayed strong green fluorescence, which was specifically quenched by Fe3+. And we develop a method for excellent sensitive and selective detection of Fe3+ with a linear range of 0.1–10 μM and a limit of detection of 0.08 μM. The method was further extended to measure the concentration of Fe3+ in actual water samples which the result is satisfactory. The synthesized G‐CDs were applied for drawing fluorescent patterns, which may be used for anti‐counterfeit. Finally, the prepared G‐CDs were used in cell imaging and detection of Fe3+ in live cells. Green fluorescent CDs (G‐CDs) were obtained using one‐pot hydrothermal treatment of Lonicera maackii fruit and exhibited excellent fluorescence characteristic and good bio‐compatibility. The G‐CDs displayed strong green fluorescence, which could specifically and sensitively detect Fe3+ at a low detection limit of detection of 0.08 μM. The G‐CDs were applied for drawing fluorescent patterns, which may be used for anti‐counterfeit. Finally, the prepared G‐CDs were used in cell imaging and detection of Fe3+ in live cells.
