Abstract
Using Raman scattering we have observed a phototransformation of C60 films on Si(100) from a face‐centered‐cubic (fcc) phase to a second solid phase leaving the C60 molecules intact. Furthermore, photoassisted oxygen diffusion into the deep bulk is detected using alpha resonance scattering. The Raman spectrum for oxygen‐doped C60 is found to be similar to the result for oxygen‐free fcc C60, and oxygen is found to harden the film against phototransformation.Keywords
