![]() | Vardeny, Zeev Valentine | Evolution of excitons and polarons in polythiophene from femtoseconds to milliseconds | We have studied the photoexcitation dynamics in electrochemically polymerized polythiophene thin films using transient photomodulation spectroscopy measured from 100 fs to 20 ms in the spectral range from 0.25 to 2.2 eV, and by the novel technique of absorption-detected magnetic resonance (ADMR). ... | Femtoseconds; Milliseconds; Photoexcitation dynamics | 1992-07 |

![]() | Vardeny, Zeev Valentine | Transient spectroscopy of excitons and polarons in C60 films from femtosecond to milliseconds | We have studied photoexcitations in C60 films using transient photomodulation and photoluminescence from 100 fs to 50 ms and absorption-detected magnetic resonance (ADMR). We show that singlet Frenkel excitons are the primary photoexcitations; their recombination kinetics in the picosecond time dom... | Transient spectroscopy; C60 films; Femtoseconds; Milliseconds | 1994-11 |
