 | Vardeny, Zeev Valentine | Exciton dynamics in single-walled nanotubes: transient photoinduced dichroism and polarized emission | Ultrafast relaxation of photoexcitations in semiconducting single-walled carbon nanotubes (S-NTs) were investigated using polarized pump-probe photomodulation (with 150 fs time resolution) and cw polarized photoluminescence (PL). Both annealed and unannealed thin NT films and D2O solutions of isola... | Exciton dynamics; Single-walled carbon nanotubes; SWNT; Transient photoinduced dichroism; Polarized emission; Ultrafast relaxation; Photoexcitations | 2005-03 |

 | Vardeny, Zeev Valentine | Exciton dynamics in soluble poly(p-phenylene vinylene) | We report studies of poly(2,5-dioctyloxy paraphenylene vinylene) thin films and solutions by a variety of transient, steady state, and nonlinear optical techniques. The energy states and optical absorption of the dominant even and odd parity excitons have been determined. Photogenerated singlet exci... | Exciton dynamics; Poly(p-phenylene vinylene); PPV; Pi-conjugated polymers | 1997 |

 | Vardeny, Zeev Valentine; Gellermann, Werner | Exciton dynamics in soluble poly(p-phenylene-vinylene): toward an ultrafast excitonic switch | We have applied a variety of ps transient and cw optical techniques to elucidate the dynamics, absorption, and emission properties of excitons in soluble derivatives of poly(p-phenylene vinylene) neat films and dilute solutions. We found that the photogenerated singlet excitons in both films and sol... | Exciton dynamics; Excitonic switch | 1997-06 |
