FULLERENE DOPED GLASSES

Optical glasses doped with a fullerene mixture of C60/C70 were made in our lab. Three peaks, corresponding to C60, C70, and a modified fulle rene (possibly its oxide), respectively, were found in the chromatogra m of high performance liquid chromatography (HPLC) analysis of the 0.1 -wt % fullerene doped phosphate glass. Depending on the doping procedu re and impurity, weak to strong interacting between C60 and its enviro nment was found by the nuclear magnetic resonance study. For both phos phate and fluorophosphate glasses with 0.01-wt % fullerene mixture dop ing, the eigen UV absorption edge showed a significant blueshift, indi cating that the bonding between the nonbridging oxygen in these glasse s was subjected to a strong change due to the fullerene doping.
