In this work, heterogeneous structures consisting of copper porphyrins and tetracene
are investigated mainly by photoemission electron microscopy (PEEM) in the vicinity
of small silver nanoparticles. As shown for silver clusters on a pristine silicon
surface, an important effect is strong coupling to the substrate leading to dramatically
altered plasmonic properties which have to be treated beyond the commonly employed
dipole approximation. By utilizing the plasmonic properties of the nanoparticles,
it was possible to locally excite molecular aggregates by the enhanced plasmonic near-field.

In dieser Arbeit werden heterogene Strukturen aus Kupfer-Porphyrin und Tetracen in
der Umgebung kleiner Silbernanopartikel primär mit dem Photoemissions-Elektronenmikroskop
(PEEM) untersucht. Wie für Silbercluster auf einer reinen Siliziumoberfläche gezeigt
werden konnte, führt die starke Kopplung zum Substrat zu drastisch veränderten plasmonischen
Eigenschaften, welche jenseits der üblich verwendeten Dipolnäherung behandelt werden
müssen. Durch Ausnutzen der plasmonischen Eigenschaften der Nanopartikel konnten molekulare
Aggregate lokal, durch das verstärkte Nahfeld, angeregt werden.
