摘要
We report the photoinduced absorption of the oxygen free C-60 thin film. The thin films of oxygen free C-60 are produced by evaporation of the C-60 powder onto a sapphire substrate. At energies between 1.65 eV and 2.25 eV, two peaks are observed; one at about 1.99 eV and the other one at about 2.25 eV which is broader than the former peak. In the case of the oxygenated film, there exists an another peak at about 1.75 eV in addition to the above two peaks. From the time resolved study of the peak at 1.92 eV, we can conclude that the lifetime of this peak is 40 mu s in the case of the oxygenated film. In the case of the oxygen free film, however, we can not find a clear decaying behavior up to 30 mu s.
