Abstract

The photoluminescence (PL) spectra of C₆₀ and C₇₀ in toluene, as films on silicon and as KBr pellet, were obtained as a function of temperature. Different emission profiles are observed between the fullerenes in solution and in the solid form. The PL spectra of the C₆₀ solids are similar regardless of their substrates, while those of C₇₀ show different emission profiles between the films on silicon and the pellet, which is believed to be due to the substrate-dependent stacking disorder resulting from the nonspherical shape of the molecule. The changes in emission intensity and profile upon temperature are observed in the PL spectra of solid C₆₀ and C₇₀, suggesting the strong influence of rotational diffusion. The vibrational mode progressions are identified from the low-temperature photoluminescence spectra of C₆₀ and C₇₀.
