Paper Abstract

We report the successful preparation of a solid solution of C60 in a silicon dioxide (SiO2) glass matrix by means of sol-gel chemistry. Raman spectroscopy and x-ray diffraction were used to verify that our synthetic route produced glasses with a homogeneous dispersion of intact fullerenes. The vibrational spectrum of C60 is preserved in the C60/SiO2 gel glass. Raman and X-ray diffraction data confirm that the C60 is microscopically dispersed, and does not form detectable phase-separated, microcrystalline regions. We report preliminary observations of optical limiting in these gels, with intensity and concentration dependence consistent with that observed for C60 in solution.
