Abstract : Solid films of C60 deposited on CaF2 under ultra-high vacuum show luminescence in the 700-1100nm spectral range at 20K. A 1400 cm-1 progression in the ag soccerball inflation mode is observed. The low-temperature absorption spectrum exhibits similar fine structure. The characterization of vibronic splittings in the ground and emitting state and the transition intensity mechanism are discussed.
