Vardeny, Zeev Valentine | Ultrafast femtosecond relaxation processes in luminescent and nonluminescent conducting polymers | We have employed the time-resolved photomodulation (PM) technique to study the photoexcitation dynamics in a luminescent (Si-PT) and nonluminescent ( s-(CH)x ) conducting polymers in the low signal limit. In each polymer, we identify two exponential decay processes in the PM decay, with characterist... | Ultrafast femtosecond relaxation; Femtosecond spectroscopy; Pump-and-probe technique; PM decay; Polarization memory; Bi-exponential response | 1997 |
