 | 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 | Photoexcitation dynamics and laser action in solutions and films of PPE-PPV copolymer | We used a variety of ultrafast and steady-state spectroscopy techniques to study the photoexcitation dynamics and laser action in dilute and concentrated solutions and in thin films of poly(phenylene-ethynylene)/ poly(phenylene-vinylene) [PPE-PPV] copolymer. We found that the primary photoexcitatio... | Photoexcitation dynamics; Laser action; PPE-PPV copolymers | 2004-04 |

 | Vardeny, Zeev Valentine | Photoexcitation dynamics in C60-doped PPV under bias illumination | We have studied photoexcitation dynamics in pristine and C60-doped PPV films under bias Olumination by photoinduced absorption (PA), optically-detected magnetic resonance (ODMR), and electromodulated PA (EPA). Intrachain polaron pair species are the dominant excitations under these conditions. The p... | Photoexcitation dynamics; C60-doped PPV; Bias illumination; PPV films; Photoinduced absorption; ODMR; Electroabsorption | 1996 |

 | Vardeny, Zeev Valentine | Photoexcitation dynamics in polyacetylene probed by transient photoinduced resonant Raman scattering | We have measured photoexcitation dynamics in the picosecond time domain in fully trans and partially isomerized (CH)X and (CD)X films with different cis/trans content ratios, using the technique of transient photoinduced resonant Raman scattering. Following the distinctively different decay kineti... | Photoexcitation dynamics | 1992-05 |

 | Vardeny, Zeev Valentine | Photoexcitation dynamics in regioregular and regiorandom polythiophene films | Using a variety of optical probes techniques we studied the photoexcitation dynamics in thin films of poly-3-hexyl thiophene with regioregular order that forms lamellae structures with increased interchain interaction, as well as regiorandom order that keeps a chainlike morphology. In regiorandom fi... | Photoexcitation dynamics; Regio-regular; Regio-random; Polythiophene films | 2001-11 |
