Product Description


Among heavy metal-free quantum dots (QDs), indium (In)-based ones have attracted much attention due to their high quantum yield, good emission tunability, and low toxicity, becoming an ideal choice for optoelectronic and imaging applications. In order to further enhance the photoluminescence (PL) properties of III-V semiconductor QDs, Alfa Chemistry has prepared core/shell fluorescent nanomaterials with indium phosphide (InP) as the core and zinc sulfide (ZnS) as the shell, and the surface is wrapped by hydrophilic ligands. If you need, please contact us immediately.
