Room temperature synthesis of cubic nanocrystalline CdSe in aqueous solution

Reaction of an alkaline selenium solution with an aqueous solution of cadmi um complex produces cubic nanocrystalline CdSe with an average particle siz e of 5 nm at room temperature under atmospheric pressure, The product was c haracterized through XRD, TEM, and XPS. The alkaline selenium solution make s CdSe crystallize well in aqueous solution. The use of cadmium complex ins tead of cadmium ion as a reagent can greatly reduce the byproduct, Furtherm ore the synthesis is performed conveniently and safely. (C) 2000 Academic P ress.
