Abstract
A method of manufacturing nanoparticles of a photoluminescent material, including the successive steps of: a) forming nanometer-range particles of said photoluminescent material; b) forming a dispersion containing the particles in a non-aqueous solvent, the dispersion further containing at least one surface agent; c) placing the dispersion in an autoclave at a pressure in the range from 2 MPa to 100 MPa; and d) recovering the particles.
