摘要：

The luminescence spectra of C60 and C70 have been recorded in glassy toluene solution at 77 K and as neat solids at 5 K. The C70 spectrum consists of two band systems each with resolved vibronic structure. The red system of C70 begins at 15012 cm-1, exhibits a lifetime of < 20-mu-s and is assigned as S1 --> S0 fluorescence. The infrared emission system begins at 12614 cm-1, decays with a 30 ms lifetime and is assigned as T1 --> S0 phosphorescence. A weak luminescence maximum at 13579 cm-1 is assigned tentatively as the S1 --> S0 fluorescence of C60.
