  • Patent number: 5474591
    Abstract: The present invention relates, in general, to a method of synthesizing nanocrystals and, in particular, to a method of synthesizing III-V semiconductor nanocrystals in solution at a low temperature and in a high yield. The method comprises the combination of mixing a Na/K alloy with an excess of Group VA element (E) in an aromatic solvent to form a (Na/K).sub.3 E pnictide, and subsequently mixing the pnictide with a Group IIIA trihalide (MX.sub.3) in a coordinating solution to form a suspension that includes the nanocrystalline semiconductor.
