Silica-coated ZnS quantum dots as fluorescent probes for the sensitive detection of Pb2+ ions
Source abstract
Abstract
The silica-coated ZnS quantum dots (ZnS@SiO2 QDs) were prepared via a simple and environmentally friendly process. The oil-soluble ZnS cores were successfully transferred to water by the coating of SiO2 shells. The QDs exhibited satisfying dispersion and luminescent properties in water. The ZnS@SiO2 QDs were directly used as fluorescent probes for heavy metal ions without the addition of any buffer solution. The luminescence of QDs was extremely sensitive to Pb2+ ions, and the fluorescence quenching was well described by the Stern–Volmer equation, with an even quenching constant for the Pb2+ ions samples concentration ranging from 10−9 to 2.6 × 10−4 M. An extended hypothesis based on the traditional cation exchange mechanism is proposed to analyze the most significant fluorescence quenching effect by Pb2+ ions. Studies show that ZnS@SiO2 QDs have great potentials to be a sensor for Pb2+ analysis at low to high concentrations.
