 | Vardeny, Zeev Valentine | Excited-state relaxation in ∏-conjugated polymers | We study ultrafast relaxation processes of odd- (Bu) and even-parity (Ag) exciton states in poly(p-phenylene vinylene) derivatives. The Bu states are studied using a regular two-beam pump-and-probe spectroscopy, which can monitor vibronic relaxation and exciton diffusion. In order to observe the A... | Ultrafast relaxation; Excited-state relaxation; pi-conjugated polymers; PPV | 2002-05 |
