Product Description
Water-soluble CdTe/CdSe/ZnS quantum dots (QDs) are core/shell/shell fluorescent nanomaterials with cadmium telluride (CdTe) as the core, cadmium selenide (CdSe) and zinc sulfide (ZnS) as the shell and the surface is wrapped by hydrophilic ligands. The water-soluble CdTe/CdSe/ZnS QDs prepared by Alfa Chemistry have an average quantum yield of up to 70%. In addition, they have good photostability, chemical stability and biocompatibility. These properties make them widely used in bioimaging and optoelectronic devices.
