method and device for the production of stable endohedralen fullerenes, the structure of z at cx with bigger 60 x

摘要

A process is disclosed for producing stable endohedral fullerenes of structure Z@Cx, in which x /= 60. A Z-atom is implanted in the fullerenes and both fullerenes and low energy accelerated Z-particles are produced at the same time and interact with each other in a vacuum vessel. The fullerenes are then withdrawn from the vacuum vessel, dissolved in a solvent and dried. Atoms of non-metals and metalloids are used as Z-atoms. The fullerenes are produced by vapour phase deposition of Cx on a substrate and and the accelerated Z-particles are produced by an ion source and directed onto the growing fullerene layer on the substrate. Alternatively, the fullerenes are produced by evaporating Cx in a furnace through which flows a gas mixture which contains the material to be implanted and the accelerated Z-particles are produced by a high-voltage gas discharge in the same furnace. The disclosed device for producing endohedral fullerenes by means of a high-voltage gas discharge has a cathode which is provided with cooling means and/or has an enlarged surface.
