Surface Layering of suspended Au-Nanoparticles — •Volker Schön1, Patrick Huber1, Philip Born2, and Tobias Krauss21Saarland University, 66123 Saarbrücken, Germany — 2Leibniz-Institut für Neue Materialien gGmbH, 66123 Saarbrücken, Germany

We present x-ray reflectivity measurements performed on our home made spectrometer showing that thiolated Au-nanoparticles suspended in toluene constitute layers at the toluene-air interface.

The experiments were performed in a closed cell with virtually no evaporation taking place, the height of the liquid being stable over several days.

The number and density of these layers strongly depends on the concentration of said suspensions and is also influenced by temperature.
