Physical vapor deposited copper phthalocyanine on silver clusters on graphite

Description

Nanostructures can be used as plasmonic light sources [1] for local generation of excitons in organic semiconductors. This is a promising pathway to transfer energy in molecular aggregates from a defined starting point over longer distances via exciton propagation. In order to establish a suitable geometry of such a hybrid system, we are interested in the role of metallic clusters during subsequent molecular growth. Mass-selected silver nanoparticles are produced in a gas-phase cluster source and deposited onto a pristine HOPG surface. Afterwards, we use in-situ photoemission electron microscopy (PEEM) to monitor the physical vapour deposition of copper phthalocyanine (CuPc) molecules [2,3] on such surfaces. We observe a Stranski-Krastanov growth during deposition of CuPc and afterwards some morphology changes of the nanocrystallites.
