摘要：

Photoacoustic spectroscopy (PAS) measurements, which are sensitive to weak optical absorption, were performed on C-60 powder, C-60 thin films and C-60 single crystal, in different crystallized state. Amorphous C-60 thin film shows two absorption shoulders at 1.70eV and 1.96eV, respectively, however, single crystal C-60 has a direct forbidden transition at 1.82eV, consistent with the energy gap of crystallized C-60 powder.
