 | Vardeny, Zeev Valentine | Optical probes of photoexcitations in fullerene thin films from femtoseconds to milliseconds | We have studied photoexcitations in various fiillerene thin films using transient photomodulation and photoluminescence from 100 fs to 50 ms and absorption-detected magnetic resonance (ADMR). We show that singlet Frenkel type excitons are the primary photoexcitations; their recombination kinetics in... | Photoexcitations; Femtosecond; Transient photomodulation; Transient photoluminescence; Frenkel type excitons; Triplet excitons | 1995 |

 | Vardeny, Zeev Valentine | Transient spectroscopy of Frenkel and charge transfer excitons in α-sexithienyl films | Photoexcitations dynamics are investigated in a-sexithienyl nanocrystalline films using transient photomodulation in a spectral range from 0.4 to 2.5 eV and time domain from 200 fs to 50 ms. We identify intrachain and interchain excitations. The former are even parity excitons with ultrafast dynami... | Transient spectroscopy; Excitons; Frenkel exciton; Charge transfer exciton; Transient photomodulation | 1997-10 |

 | Vardeny, Zeev Valentine | Ultrafast response of surface electromagnetic waves in an aluminum film perforated with subwavelength hole arrays | The ultrafast dynamics of surface electromagnetic waves photogenerated on aluminum film perforated with subwavelength arrays of holes was studied in the visible spectral range by the technique of transient photomodulation with ~100 fs time resolution. We observed a pronounced blueshift of the resona... | Subwavelength hole arrays; Nanohole arrays; Transient photomodulation; Plasmonic lattices; Surface electromagnetic waves; SEW; Periodic subwavelength arrays | 2008-02 |
