Water-soluble CdSe/ZnS quantum dots (QDs) are semiconductor nanocrystals with a core of cadmium selenide (CdSe) and a shell of zinc sulfide (ZnS). ZnS is non-toxic and chemically stable under any conditions. It can not only reduce the toxicity of cadmium ions, but also improve the quantum yield and the photostability of QDs. Water-soluble CdSe/ZnS QDs prepared by Alfa Chemistry are known for their tunable emission properties. If you need, please contact us immediately.
