CONTINUOUS PROCESS FOR THE SYNTHESIS OF TERNARY OR QUATERNARY SEMICONDUCTING NANOPARTICLES BASED ON IB, IIIA, VIA ELEMENTS OF THE PERIODIC CLASSIFICATION

摘要

A process for the continuous production of ternary or quaternary semiconducting nanoparticles based on IB, IIIA, VIA elements of the periodic classification, in particular low-toxic AglnS₂; and CuInS₂ in the liquid phase is described. A uniform size of semiconducting nanoparticles is obtained in a size range from 1 nm to 20 nm, showing chalcopyrite or wurzite crystal structure. The size and crystal structure of the semiconducting nanoparticle can be controlled by adjusting reaction parameters in particular concentration, temperature, flow and selected ligands.
