(a) The comparison of the fluorescence quenching intensity of the IUST-3 (1 mg) in water (2 ml) among the different anions (1 mM, 100 µl), (b) Photoluminescence spectra of the IUST-3 with gradual addition of the CrO42− anion (1 mM, 10 µL addition each time), (c) Stern–Volmer plot of I0/I versus the CrO42− anion concentration in the IUST-3 aqueous suspension (insert: enlarged view of a selected area), (d) Selective detection of the CrO42− anion on the IUST-3 in the presence of different aromatic compounds in water.
