Process for preparing endohedral fullerenes or fullerene derivatives

摘要

Amounts of endohedral fullerenes or fullerene derivatives which can be isolated macroscopically are to be prepared efficiently irrespective of the type of doping agent to be implanted. To that end, according to the invention, fullerenes or fullerene derivatives are applied to a target and irradiated in the solid phase with low-energy ions having kinetic energy of between 5 eV and 500 eV of the doping agents to be implanted. The application of fullerenes or fullerene derivatives and irradiation are carried out simultaneously or successively. The energy of the ions and the irradiation dose at which most of the ions of the doping agents to be implanted penetrate the fullerene or fullerene derivatives to be applied to the target are determined in series of measurements.
