摘要：
We report a Brillouin scattering study of the product resulting from laser irradiation of C60 single crystal. We found that, under high fluence laser irradiation in the presence of oxygen, a new structure is formed; the acoustic properties of this material are different from pristine solid C60 and are similar to those of slow polymers or highly porous materials such as carbon aerogels. Scanning electron microscopy analysis of the material formed under irradiation confirms the formation of a spongy ramificated structure. The role of oxygen in driving fullerene cage-opening reactions is discussed.
