    • Anisotropic Emission from Multilayered Plasmon Resonator Nanocomposites of Isotropic Semiconductor Quantum Dots 

      Ozel, T.; Nizamoglu, S.; Sefunc, M.A.; Samarskaya, O.; Ozel, I. O.; Mutlugun, E.; Lesnyak, V.; Gaponik N.; Eychmuller, A.; Gaponenko, S. V.; Demir, Hilmi Volkan (American Chemical Society, 2011-01-19)
      We propose and demonstrate a nanocomposite localized surface plasmon resonator embedded into an artificial three-dimensional construction. Colloidal semiconductor quantum dots are assembled between layers of metal nanoparticles ...

    • Bio-nanohybrids of quantum dots and photoproteins facilitating strong nonradiative energy transfer 

      Seker U.O.S.; Mutlugun, E.; Hernandez-Martinez, R. L.; Sharma, V. K.; Lesnyak, V.; Gaponik N.; Eychmuller, A.; Demir, Hilmi Volkan (Royal Society of Chemistry, 2013-05-21)
      Utilization of light is crucial for the life cycle of many organisms. Also, many organisms can create light by utilizing chemical energy emerged from biochemical reactions. Being the most important structural units of the ...

    • Brightly luminescent Cu-Zn-In-S/ZnS Core/shell quantum dots in salt matrices 

      Lox, J. F. L.; Eichler, F.; Erdem, Talha; Adam, M.; Gaponik, N.; Demir, Hilmi Volkan; Lesnyak, V.; Eychmüller, A. (De Gruyter, 2019)
      In the past decades cadmium-free quantum dots (QDs), among which are quaternary colloidal Cu-Zn-In-S/ZnS (CZIS/ZnS) core/shell nanocrystals (NCs), have attracted great scientific interest. Particularly, their low toxicity ...

    • Colloidal Nanocrystals Embedded in Macrocrystals: Robustness, Photostability, and Color Purity 

      Otto, T.; Mueller, M.; Mundra, P.; Lesnyak, V.; Demir, Hilmi Volkan; Gaponik N.; Eychmuller, A. (American Chemical Society, 2012-09-14)
      The incorporation of colloidal quantum dots (QDs) into ionic crystals of various salts (NaCl, KCl, KBr, etc.) is demonstrated. The resulting mixed crystals of various shapes and beautiful colors preserve the strong ...

    • Flexible and fragmentable tandem photosensitive nanocrystal skins 

      Akhavan S.; Uran, C.; Bozok, B.; Gungor K.; Kelestemur Y.; Lesnyak, V.; Gaponik N.; Eychmüller A.; Demir, Hilmi Volkan (Royal Society of Chemistry, 2016)
      We proposed and demonstrated the first account of large-area, semi-transparent, tandem photosensitive nanocrystal skins (PNSs) constructed on flexible substrates operating on the principle of photogenerated potential ...

    • Multiexciton generation assisted highly photosensitive CdHgTe nanocrystal skins 

      Akhavan S.; Cihan, A. F.; Yeltik A.; Bozok, B.; Lesnyak, V.; Gaponik N.; Eychmüller A.; Demir, Hilmi Volkan (Elsevier Ltd, 2016)
      Multiexciton Generation (MEG) enabled by the photogeneration of more than one electron-hole pairs upon the absorption of a single photon observed in colloidal semiconductor nanocrystals (NCs) is an essential key to high ...

    • Structural tuning of color chromaticity through nonradiative energy transfer by interspacing CdTe nanocrystal monolayers 

      Cicek, N.; Nizamoglu, S.; Ozel, T.; Mutlugun, E.; Karatay, D. U.; Lesnyak, V.; Otto, T.; Gaponik N.; Eychmuller, A.; Demir, Hilmi Volkan (American Institute of Physics, 2009-02-09)
      We proposed and demonstrated architectural tuning of color chromaticity by controlling photoluminescence decay kinetics through nonradiative Forster resonance energy transfer in the heterostructure of layer-by-layer spaced ...
