Abstract: A partial cation-exchange method is described in which the lability is considered for synthesizing PbSe/CdSe core/shell nanocrystal quantum dots (NQDs). The NQDs have undergone additional shell growth in order to produce PbSe/CdSe/ZnS core/shell NQDs that have represented initial steps toward bright, biocompatible near-infrared optical labels.
