Stable and low-threshold optical gain in CdSe/CdS quantum dots : an all-colloidal frequency up-converted laser

Stable and low-threshold optical gain in CdSe/CdS quantum dots : an all-colloidal frequency up-converted laser

An all-solution processed and all-colloidal laser is demonstrated using tailored CdSe/CdS core/shell quantum dots, which exhibit highly stable and low-threshold optical gain owing to substantially suppressed non-radiative Auger recombination.
