Abstract: A population of nanocrystals including a core comprising a first semiconductor material comprising one or more elements of Group IIIA of the Periodic Table of Elements and one or more elements of Group VA of the Periodic Table of Elements, and a shell disposed over at least a portion of the core, the shell comprising a second semiconductor material, wherein the nanocrystal is capable of emitting light having a photoluminescence quantum efficiency of at least about 30% upon excitation. Also disclosed is a nanocrystal comprising a nanocrystal core and a shell comprising a semiconductor material comprising at least three chemical elements and obtainable by a process comprising adding a precursor for at least one of the chemical elements of the semiconductor material from a separate source to a nanocrystal core while simultaneously adding amounts of precursors for the other chemical elements of the semiconductor material. Devices including nanocrystals are disclosed.
