Abstract A composite material based dual-emission probe for Fe3+ was prepared by the hybridization of a three-dimensional framework with CdSe/ZnS quantum dots (QDs)-doped silica nanoparticles. The obtained probe showed characteristic fluorescence emissions of CdSe/ZnS QDs (red) and Cd-metal-organic framework (MOF, blue) under a single exciation wavelength. Upon the detection of Fe3+, only the fluorescence of Cd-MOF was quenched, whereas the red fluorescence of CdSe/ZnS QDs particles was mostly reserved. Consequently, the variation of the two fluorescence intensity ratios displays a continuous color change from blue to red upon exposure to different amounts of Fe3+ ions, which can be easily observed under a UV lamp.
