 | 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 |

 | Vardeny, Zeev Valentine | Spin and spectral signatures of polaron pairs in ∏-conjugated polymers | We have studied polaron pair photoexcitations in a variety of p-conjugated polymer films by photoinduced absorption (PA) and optically detected magnetic resonance (ODMR). Both luminescent and nonluminescent polymers have been studied. An exchange interaction between polarons broadens their magneti... | Spin signatures; spectral signatures; Photoinduced absorption; Photoexcitation | 1997-08 |

 | Vardeny, Zeev Valentine | Studies of charged excitations in ∏-conjugated oligomers and polymers by optical modulation | We have studied photogenerated charged excitations in sexithiophene and a variety of p-conjugated polymers by photoinduced absorption (PA) and PA-detected magnetic resonance. We found distinct spin signatures for polarons and bipolarons, which enabled us to separate their contributions to the PA spe... | Pi-conjugated oligomers; Pi-conjugated polymers; Charged excitations; Optical modulation; Spin signatures; Bipolarons; Photoexcitation | 1996-08 |
