For cadmium telluride (CdTe) quantum dots (QDs), cadmium sulfide (CdS) is one of the most promising capping materials. This is due to the fact that the lattice mismatch between the CdTe core and the outer CdS shell is small enough not to generate many defects. Alfa Chemistry has prepared core/shell fluorescent nanomaterials with CdTe as the core and CdS as the shell, and the surface is wrapped by hydrophilic ligands. If you need, please contact us immediately.
