Optical and photochemical properties of C60 films

Abstract
Results of optical studies of thin solid C60 films are presented which highlight some of the unusual optical phenomena observed in fullerene-derived materials. Results of several experiments to determine quantitatively the optical dielectric function are first presented and discussed. We also present results on two different phototransformations of C60 films from a toluene-soluble to a toluene-insoluble state. These processes may have photolithographic application. The first involves the photopolymerization of C60, and the second is a photo-induced intercalation of di-oxygen into the C60 lattice leading to a film with composition C60(O2).
