Abstract
A method of manufacturing a nanocrystallite from a M-containing salt forms a nanocrystallite. The nanocrystallite can be a member of a population of nanocrystallites having a narrow size distribution and can include one or more semiconductor materials. Semiconducting nanocrystallites can photoluminesce and can have high emission quantum efficiencies.
Claims25
A method of manufacturing a nanocrystal comprising heating a mixture including a coordinating solvent, an amine or a reducing agent, a chalcogen or pnictide source, and a metal-containing compound to form a nanocrystal, wherein the metal-containing compound is free of metal-carbon bonds.
A method of manufacturing a nanocrystal, comprising:
- contacting a metal, M, or an M-containing salt, M being Cd, Zn, Mg, Hg, Al, Ga, In, or Tl, an amine, and an X donor, X being O, S, Se, Te, N, P, As, or Sb to form a mixture;
- and
- heating the mixture to form the nanocrystal.
