ABSTRACT:
Optical glasses and polymers are described that incorporate homogeneously dispersed fullerene molecules. The resultant materials may be used as optical filters, the cut-off frequency being easily adjustable by changing the fullerene content. To prepare glasses fullerene molecules are firstly functionalized by amination prior to being incorporated into a sol-gel process to prepare the glass. To prepare polymers a pre-existing polymer may be subject to fullerenation, or fullerene may be copolymerized with a selected monomer.
