Abstract
The invention relates to a method for the synthesis of glutathione-capped cadmium-telluride (GSH-CdTe) quantum dots in an aqueous medium, including the steps of: a) preparing a precursor solution of cadmium in a citrate buffer; b) adding glutathione (GSH) to the preceding mixture via strong agitation; c) adding a telluride (potassium or sodium telluride) oxyanion as a telluride donor to the preceding mixture; d) allowing the preceding mixture to react; and e) stopping the reaction by incubation at low temperature.
