Impact of plasmonic nanostructures on the optical properties of fluorinated ZnPc thin films — •Verena Kolb1, Michael Brendel1, and Jens Pflaum1,2 — 1Experimental Physics VI, Julius Maximilians University of Würzburg, 97074 Würzburg — 2ZAE Bayern, 97074 Würzburg
By adjusting the localized surface plasmon resonance (LSPR) of defined metal nanostructures either the absorption or photoluminescence of organic layers can be enhanced and thus might be an interesting approach for improving both organic solar cells and LEDs. This enhancement is caused by an increase of the near-field component of the electromagnetic field and in the case of absorption the scattering of light. In this contribution gold nanostructures were fabricated via shadow nanosphere lithography and optically and morphologically characterized. Complementary, finite difference time domain simulations were used to determine their LSPR. Finally, their impact on the optical properties of fluorinated Zn-Phthalocyanines (ZNPc), which prove to be interesting candidates for organic electronics, was investigated.
