Abstract
Described are CdTe/CdS/ZnS core/shell/shell nanocrystals, methods for making the same, and their use in biomedical and photonic applications, such as sensors for analytes in cells and preparation of field effect transistors. In particular, the disclosure provides a nanocrystal having a CdTe core, a CdS coating over the core, and a ZnS core over the CdS coating, where the nanocrystal has a photoluminescence maximum between about 650 nm and 900 nm.
