Abstract 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 Fe 3+ . And we develop a method for excellent sensitive and selective detection of Fe 3+ 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 Fe 3+ 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 Fe 3+ in live cells.
