Solar process for making fullerenes
AuthorSmalley, Richard E.
This invention provides an improved process and apparatus for making fullerenes by vaporizing carbon and conducting the resulting carbon vapor to a dark zone for fullerene growth and annealing. In one embodiment concentrated solar energy is used to vaporize carbon. In a further embodiment, concentrated solar energy may be used to improve fullerene yields by vaporizing carbon and further to prevent carbon cluster formation until the carbon vapor passes into a dark zone for fullerene growth and annealing. The invention provides an improvement to increase the yield of any known process wherein carbon is vaporized under high light conditions, the improvement comprising providing a dark zone for fullerene growth and annealing.
