      Electroluminescence by a Sm3+-diketonate-phenanthroline complex 

      Stathatos, Elias; Lianos, P.; Evgeniou, E.; Keramidas, Anastasios D. (2003)
      The development of an organic light emitting diode (OLED) based on the use of Sm3+ complex as an emitting layer was investigated. The construction process also involved the use of poly(vinylcarbazole) (PVK) as the transporter ...

      Femtosecond UV pump/near-IR probe studies of the solvent-dependent excited-state decay dynamics of chlorine dioxide 

      Hayes, Sophia C.; Cooksey, C. C.; Wallace, P. M.; Reid, P. J. (2001)
      The excited-state decay and geminate-recombination dynamics of chlorine dioxide (OClO) are investigated using UV pump/near-IR probe spectroscopy. Experiments are performed with 200-fs time resolution on OClO dissolved in ...

      Influence of grain size on ultrafast carrier dynamics in thin nanocrystalline silicon films 

      Lioudakis, Emmanouil E.; Othonos, Andreas S.; Nassiopoulou, Androula Galiouna; Lioutas, Ch B.; Frangis, N. (2007)
      The ultrafast carrier dynamics in thin nanocrystalline silicon films (10 and 20 nm thick) on quartz over a broad spectral range using optical pumping at a moderate fluence of 2.5 mJ cm2 were studied. The films were composed ...

      Optical spin injection in CuGaSe2/GaAs films 

      Itskos, Grigorios; Murray, R.; Meeder, A.; Papathanasiou, Niklas; Lux-Steiner, M. Ch (2006)
      We have investigated polarization-resolved photoluminescence in epitaxially grown CuGaSe2/GaAs(001) films. Spin-polarized excitons are optically excited both below and above the characteristic crystal field splitting of ...

      Ultrafast hole carrier relaxation dynamics in p-type CuO nanowires 

      Othonos, Andreas S.; Zervos, Matthew (2011)
      Ultrafast hole carrier relaxation dynamics in CuO nanowires have been investigated using transient absorption spectroscopy. Following femtosecond pulse excitation in a non-collinear pump-probe configuration, a combination ...
