Trasparent sol-gel thin films and monoliths containing fullerene derivatives (e.g. see Figure) are reported. The sol-gel technique provides a low-temperature method to poduce homogeneous thin films and preliminary measurements reveal that these new commposite materials, the first sol-gel materials to contain C60 or its derivatives, exhibit interesting optical limiting properties.
