A novel “turn-on” fluorescent sensor of CeO₂@MIL-88B was constructed successfully via the facile in-situ strategy. The as-obtained CeO₂@MIL-88B could be used for effectively detecting the analyte of thiabendazole (TBZ) by luminescence enhancement, which limit of detection (LOD) was as low as 0.294 μM (nearly 10.4 times smaller than that of MIL-88B). The detection behavior for TBZ exhibited the excellent selectivity and anti-interference ability. Systematic explorations were performed to shed light on the underlying mechanism of “turn-on” effect on fluorescence after adding TBZ. Moreover, the CeO₂@MIL-88B was also employed for the determination of TBZ in the real samples of orange and cucumber.
