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 ...
Photocatalytic hybrid nanocomposites of metal oxide nanoparticles enhanced towards the visible spectral range

Perkgoz, N. K.; Toru, R. S.; Unal, E.; Sefunc, M.A.; Tek, S.; Mutlugun, E.; Soganci, I. M.; Celiker, H.; Celiker, G.; Demir, Hilmi Volkan (Elsevier, 2011-04-13)

We propose and demonstrate photocatalytic hybrid nanocomposites that co-integrate TiO(2) and ZnO nanoparticles in the same host resin to substantially enhance their combined photocatalytic activity in the near-UV and visible ...
Volumetric plasmonic resonator architecture for thin-film solar cells

Sefunc, M.A.; Okyay, Ali Kemal; Demir, Hilmi Volkan (AIP Publishing, 2011-03-04)

We propose and demonstrate a design concept of volumetric plasmonic resonators that relies on the idea of incorporating coupled layers of plasmonic structures embedded into a solar cell in enhanced optical absorption for ...
