摘要

The development of sensitive and stable materials for detecting antibiotics and metal ions is essential for environmental monitoring. In this study, we successfully synthesized a fluorescent probe, Eu3+@ZnMOF, with a dual-emission property by encapsulating Eu3+ ions into a zinc-based metal–organic framework (ZnMOF). This probe demonstrated high selectivity and sensitivity for tetracycline and Fe3+ ions, featuring good anti-interference ability and cyclic stability. Interestingly, both fluorescence emission peaks of Eu3+@ZnMOF at 475 nm and 620 nm exhibited obvious fluorescence responses to tetracycline and Fe3+, respectively. The possible sensing mechanism was attributed to competitive energy absorption between Eu3+@ZnMOF and the analytes, which was confirmed by the UV-vis absorption spectra. This work highlights that Eu3+@ZnMOF can be developed as an efficient and stable ratiometric platform for the detection of environmental pollutants.
