Picosecond Time-Resolved Excited-State Studies of C-60 and C-70 Thin-Films
We have studied photoexcitations in C-60 and C-70 thin films by transient photomodulation (PM) and transient photoluminesciense (PL). For 2.17 eV excitation we find photogenerated singlet excitons in C-60 and photogenerated singlet excitons and charged carriers in C-70 Our results differ significantly from C-60 and C-70 molecules in solution.
