Abstract:
A method for producing compound semiconductor quantum particles from at least a metallic element selected from Groups IIA, IIB, IIIA, IVA, and VA of the Periodic Table and at least a non-oxygen reactant element selected from the group consisting of P, As, S, Se, and Te, said method comprising:(a) operating a heating and atomizing means to provide a stream of super-heated fine-sized fluid droplets of said at least a metallic element into a reaction chamber; (b) directing a stream of a reactant fluid medium comprising said at least a reactant element into said chamber to impinge upon and react with said stream of super-heated metal fluid droplets to form substantially nanometer-sized phosphide, arsenide, sulfide, selenide, and/or telluride compound particles; and (c) cooling and/or passivating said compound particles to form said compound semiconductor quantum particles in a solid state.
