Water-Soluble Polymer Functionalized CdTe/ZnS Quantum Dots: A Facile Ratiometric Fluorescent Probe for Sensitive and Selective Detection of Nitroaromatic Explosives



A ratiometric fluorescent probe based on dual luminescence QD/CPL for selective sensing of the nitroaromatic explosive picric acid (PA) was constructed. The observed ratiometric fluorescence intensity change allows the quantitative detection of PA with a detection limit of 9 nM.
