Samsung patents method to make display particles using zinc and sulfur
Samsung describes a chemical process for creating tiny semiconductor particles used in screens. The method mixes zinc and sulfur compounds in a liquid solution and heats them to form the nanoparticles, then adds specific metal salts to finish the structure.
In the filing’s own words
A method of preparing a semiconductor nanoparticle, a semiconductor nanoparticle, an ink composition and an electroluminescent device. The method includes: providing a reaction medium including an organic solvent; adding a zinc precursor, a sulfur precursor, and a particle including a first semiconductor nanocrystal to the reaction medium; heating the reaction medium to a reaction temperature to provide the semiconductor nanoparticle; and adding a metal halide to the reaction medium including the semiconductor nanoparticle, wherein the metal halide includes an organozinc halide and an aluminum halide.
