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. The method includes: (a) operating a heating and atomizing means to provide a stream of super-heated fine-sized fluid droplets of a selected metallic element into a reaction chamber; (b) directing a stream of a reactant element-containing fluid medium into the chamber to impinge upon and react with the 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 the compound particles to form the desired compound semiconductor quantum particles. These quantum particles are particularly useful for photo luminescence and biological labeling applications.
