A method for synthesizing a chalcogenide nanoparticle is provided. The method comprises reacting a metal component with an elemental chalcogen precursor in the presence of an organic solvent. The chalcogenide nanoparticles include ternary, binary and/or multinary chalcogenide nanoparticles and the metal component comprises metal halides or elemental metal precursors. The alkylamine solvent has a normal boiling temperature of above about 22OoC and an average particle size of from about 5 nm to about 1000 nm.

La présente invention concerne un procédé de synthèse de nanoparticules de chalcogénure. Le procédé comprend la réaction d'un composant métallique avec un précurseur de chalcogène en présence d'un solvant organique. Les nanoparticules de chalcogénure comprennent des nanoparticules de chalcogénure ternaire, binaire et à systèmes multiples et le composant métallique comporte des halogénures métalliques ou des précurseurs de métal élementaire. Le solvant à base d'alkylamine a une température d'ébullition supérieure à environ 2200C et une taille moyenne de particules comprise entre environ 5 nm et environ 1000 nm.
