摘要：
We report measurements of the optical absorption spectrum of solid C60 in the pressure range from 0 to 40 GPa. At low pressure we find a linear shift of the absorption edge of -0.14 eV/GPa eV. Above 20 GPa, the fullerenes transform irreversibly to amorphous carbon; we find no evidence of transparency greater than that of amorphous carbon produced by other means.
