摘要： A nanocrystal comprising a semiconductor material comprising one or more elements of Group IMA of the Periodic Table of Elements and one or more elements of Group VA of the Periodic Table of Elements, 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 disposed on at least a portion of the nanocrystal core, wherein the semiconductor material comprises at least three chemical elements and is 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. Populations of nanocrystals, method for preparing nanocrystals, compositions, and devices including nanocrystals are also disclosed.
