Fullerenes are generated by vaporizing carbon with a laser beam and maintaining the vaporized carbon at conditions selected to promote fullerene growth and formation. This method of fullerene generation may be used to form new compounds including fullerenes surrounding one or more metal atoms, and fullerenes wherein one or more carbon atoms have been substituted with boron or nitrogen.
