Temperature-dependent optical transmission is performed on C 60 polycrystalline films of various thicknesses with incident photon energies from 1.46 to 2.07 eV. Remarkable absorption peaks together with the dependence of peak intensity on film thickness are observed and explained in terms of an ener
