The photoluminescence (PL) spectra of C6" and CT0 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 C&solids are similar regardless of
The triplet states of C6,, and C,,, (fullerenes) in solid phase at 3 and 77 K are detected by the time-resolved EPR technique. The observed time-resolved EPR spectra and the time profiles of the transient signals indicate that the geometries of Cw and CT0 are distorted from the soccerball geometry (
Time-resolved fluorescence depolarisation spectroscopy was used for measuring rotational reorientation times ( 7r) of C& and C,,, in toluene as a function of temperature. The anisotropy decay could not be monitored at any temperature (296-l 91 K) . The plausible reasons could be either washing off a
