摘要： A method for producing nanoscale organic solid particles is proposed, starting from the corresponding sublimable organic solid as raw material, in the form of particles having an average particle diameter in the range of from 1 μm to 10 mm, which are dispersed in a carrier gas so as to obtain a dispersion, which is relaxed in a convergent nozzle, which is followed by an expansion chamber, and wherein openings are provided rotationally symmetrically about the midaxis of the expansion chamber in the wall of the expansion chamber which comprises the product outlet opening, through which openings a secondary gas flow is injected comprising an inert gas carrier and molecules, ions or nanoscale particles contained in molecularly disperse form therein, which are different from the raw material and which have an average particle diameter that is less than the average particle diameter of the product.
