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.

A method of synthesizing a Group III-V nanocrystalline semiconductor comprising:
- i) forming a mixture comprising a pnictide ((Na/K).sub.3 E) by mixing a sodium/potassium (Na/K) alloy with an excess of Group VA (E) element in an aromatic solvent
- ii) mixing the (Na/K).sub.3 E resulting from step (i) with a solution comprising a Group IIIA trihalide (MX.sub.3) in the presence of a coordinating solvent so that a suspension comprising said Group III-V nanocrystalline semiconductor (ME) and (Na/K)X is formed;
- and
- iii) isolating ME resulting from step (ii).
