Abstract
Pure crystals: Ion exchange of semiconductor nanocrystals yielded materials with poor optoelectronic properties such as low photoluminescence quantum yields. The reason for the low quantum yields of these nanocrystals are impurities at the level of a few atoms per nanocrystal. Cation-exchanged nanostructures, however, could be purified post exchange from such impurities resulting in high-quality nanocrystals (see picture).
