 | Vardeny, Zeev Valentine | Optical probes of photoexcitations in fullerene thin films from femtoseconds to milliseconds | We have studied photoexcitations in various fiillerene thin films using transient photomodulation and photoluminescence from 100 fs to 50 ms and absorption-detected magnetic resonance (ADMR). We show that singlet Frenkel type excitons are the primary photoexcitations; their recombination kinetics in... | Photoexcitations; Femtosecond; Transient photomodulation; Transient photoluminescence; Frenkel type excitons; Triplet excitons | 1995 |
