Product Description
Water-soluble ZnCdS/ZnS quantum dots (QDs) are semiconductor nanomaterials with core-shell structure and surface wrapped by hydrophilic ligands. Among them, zinc cadmium sulfide (ZnCdS) ternary alloy is used as the core, and zinc sulfide (ZnS) is used as the shell. This type of QDs can exhibit specific optical and electronic properties, and the alloy composition can be tuned to achieve the desired properties.
