III-V nanoparticles and method for their manufacture

摘要

A method for the manufacture of a III-V compound in the form of nanoparticles, such as those used in semi-conductors. The reaction proceeds at atmospheric pressure in a reaction solution by the reaction of a III compound source and a V compound source. The reaction proceeds in solvent of high boiling point. The solvent contains a stabilizer and a base. The manufactured III-V compound is precipitated from the reaction solution, isolated, purified and analyzed.

1. A method for manufacturing particles of a III-V compound comprising gallium or indium as a III component, and phosphorous or arsenic as a V component, said method comprising:
(i) adding a reducing agent to a heated solution, wherein said heated solution comprises:
a solvent;a stabilizer;a Group III compound selected from the group consisting of Group III salts and Group III oxides; anda Group V compound selected from the group consisting of metal phosphides and metal arsenides, wherein the Group V compound is a phosphide or an arsenide of magnesium or calcium,to form a resultant solution; (ii) heating the resultant solution; (iii) isolating particles of the III-V compound as a precipitate from the heated resultant solution; and (iv) purifying the particles.
