We have studied photoexcitations in C-60 and C-70 thin films by transi
ent photomodulation (PM) and transient photoluminesciense (PL). For 2.
17 eV excitation we find photogenerated singlet excitons in C-60 and p
hotogenerated singlet excitons and charged carriers in C-70 Our result
s differ significantly from C-60 and C-70 molecules in solution.
