Claim Text:
1. A process for preparing a composition of mixed crystalline particles including at least one element from column 13 of the periodic table selected from the group consisting of gallium, aluminum, indium, boron, and thallium, and at least one element from column 15 of the periodic table selected from the group consisting of nitrogen, phosphorus, arsenic, antimony, bismuth, in which: at least one precursor comprising at least one element E1 from column 13 is chosen, at least one precursor comprising at least one element E2 from column 15 is chosen, a liquid solution is prepared by solubilising in a non-aqueous solvent medium at least one first precursor chosen from a coordination complex comprising at least one element E1 from column 13, in the presence of at least one compound, called a ligand, that does not have a reducing action with respect to the precursors and is chosen to facilitate the formation of mixed monocrystalline nanoparticles, said liquid solution is brought into contact with at least one second precursor chosen from the hydrides of at least one element E2 from column 15, and said liquid solution is subjected to reaction conditions capable of permitting contacting of the precursors and bringing about a reaction that produces mixed crystalline particles, wherein the reaction is carried out in the absence of an agent acting as a reducing agent for the nanoparticle-forming reaction, and at a temperature in a range from ambient temperature to 50° C.
