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; Ehrenfreund, Eitan A. | Polaron spin-lattice relaxation time in ∏-conjugated polymers from optically detected magnetic resonance | We describe a method for obtaining the polaron spin-lattice relaxation time TSL in ∏-conjugated polymers by measuring the optically detected magnetic resonance (ODMR) dynamics as a function of microwave power and laser intensity. The peculiar ODMR dynamics is well described by a spin dependent re... | pi-conjugated polymers; Optically detected magnetic resonance; ODMR; MEH-PPV | 2007-10 |

Vardeny, Zeev Valentine | Spin and spectral signatures of polaron pairs in π-conjugated polymers | We have studied polaron pair photoexcitations in a variety of π-conjugated polymer films by photoinduced absorption (PA) and optically-detected magnetic resonance (ODMR). An exchange interaction between polarons broadens the ODMR spectrum, permitting the unambiguous identification of the polaron pa... | Polaron pair; ODMR; Photoinduced absorption; Spin signatures; Spectral signatures; pi-conjugated polymers | 1997 |
