Influence of core size and compression on the conformation and vertical position of plasmonic core-shell microgels at air/water interfaces
We want to study plasmonic core-shell microgels confined at air/water interfaces using neutron reflectometry. Through this we want to gain knowledge on the influence of the size of the gold cores and uniaxial compression on the conformation and vertical position at the interface. This information is crucial for understanding the optical response of the monolayers and thus for development of new colloid-based materials with applications in colour-tunable materials, sensing and lasing. We propose to use gold-PNIPAM core-shell microgels with two differently cross-linked shells. Through postmodification of the gold cores we will be able to study monolayers of the same two microgel systems but with significantly overgrown cores. The scattering contrast will be varied through the subphase, i.e. by mixing D2O and H2O. The obtained results will be compared to ex-situ results from microscopy after transfer of the monolayers to solid substrates. Furthermore, we will use in-situ and ex-situ spectroscopy to investigate the plasmonic properties of the monolayers. Through this we will generate a comprehensvie understanding of the structure, arrangement and optical properties of such monolayers.
