PROCESS FOR PREPARING NANO-SIZED CADMIUM AND CADMIUM CHALCOGENIDE COLLOID IN ORGANIC SOLVENTS

摘要

A method for manufacturing nano-sized cadmium and cadmium chalcogenide colloid in an organic solvent is provided to show excellent dispersibility in organic solvents, crystalline and purity as well as uniform particle size distribution. A method for manufacturing nano-sized cadmium and cadmium chalcogenide colloid in an organic solvent comprises: a first step of heating a reactant containing cadmium aminoalkoxide compounds in order to transform it to a cadmium-containing nanoparticle; and a second step of separating the obtained cadmium-containing nanoparticle. The reactant containing a precursor material selected among S, Se and Te can be added in the first step and therefore cadmium chalcogenide nanoparticles are obtained.
