The type II structure of these nanocrystals allows the shell to confine only one of the charge carriers (electrons/holes). The recombination of the electron-hole pair across the heterojunction is engineered to be efficient although the radiative transition is spatially indirect. Such near-IR emission is in the wavelength range not achievable by either of the original semiconductors alone. In literature, tunable emission energies in the visible to near-IR spectral range are documented for type-II quantum dots. The new structure of CdTeSeS quantum dots makes them more tunable for PL emission from 650 nm to over 900 nm. Furthermore, the type-II quantum dots are nearly monodispersed, which provides excellent optical performance and reliability.
