Anovel smartphone-assisted fluorescence sensor was prepared for determination of antimony ions (Sb(3+)). It was synthesized by encapsulatingglutathione (GSH)-decorated gold nanoclusters (AuNCs) into zeolitic imidazolate frameworks (ZIF-8) (denoted as AuNCs/ZIF-8). Based on the strong fluorescence quenching caused by the addition of Sb(3+) ions, the AuNCs/ZIF-8 was designed for determination of Sb(3+) ions. The basic reason for fluorescence quenching of AuNCs caused by Sb(3+) ions is the reduction of Au (I) to Au (0), which is proved by the XPS....
