Synthesis of Highly Luminescent Glutathione-Capped CdTe-Mn/ZnS Quantum Dots

Abstract:

A green synthetic route is reported for quickly synthesis of highly luminescent CdTe-Mn/ZnS quantum dots (QDs) in aqueous solution. Glutathione (GSH) was used as capping reagent and thioacetamide (TAA) as sulfur source for growth of ZnS shell on the CdTe-Mn QDs. At the optimum reaction conditions, the results indicate that the GSH-capped CdTe-Mn/ZnS QDs exhibit high fluorescence QYs and the best QY is 58%. These GSH-capped core-shell QDs exhibit excellent colloidal and photostability. This method is simple and environmentally friendly.
