 | Vardeny, Zeev Valentine | Photogeneration action spectroscopy of neutral and charged excitations in films of ladder-type poly(para-phenylene) | The photogeneration quantum efficiency action spectra of long-lived neutral and charged excitations in films of a ladder-type poly(para-phenylene) were measured. We found that both triplet and polaron action spectra show, in addition to a step function increase at the optical gap, a monotonic rise a... | Photogeneration; Neutral excitations; Charged excitations; pi-conjugated polymers; Transient spectroscopy | 1999-04 |

 | Vardeny, Zeev Valentine | Photogeneration and recombination processes of neutral and charged excitations in films of a ladder-type poly(para-phenylene) | We introduce a version of the cw photomodulation technique, measured far from the steady state, for obtaining the quantum efficiency, η, of long-lived photoexcitations in p-conjugated polymers. We apply this technique to films of a ladder-type poly(para-phenylene) [mLPPP] for studying the photoge... | Photogeneration; Recombination process; Neutral excitations; Charged excitations; Ladder-type poly(para-phenylene) | 1999-08 |
