Seminar

Synthesis, Surface Chemistry and Assembly of Plasmonic Nanoparticles towards New Optical Materials

Gold nanoparticles interact strongly with light which is the foundation of their diverse applications in sensing, surface- enhanced spectroscopies, plasmonic heating and catalysis. In this seminar, the fundamentals of synthesis, surface functionalization and characterization of plasmonic nanoparticles will be discussed. Their characteristic localized surface plasmon resonances in the optical range are already valuable in such fundamental studies. Beyond the optical regime, these nanoparticles also scatter X-rays efficiently, enabling detailed investigations of their structure, dynamics and interactions, as well as their use as tracer materials. When assembled into well-ordered superstructures, new collective plasmonic modes emerge, leading to even stronger light-matter coupling and fundamentally altering the materials’ properties. By controlling the hierarchical structure - from individual nanoparticles to superlattices - we can tailor both the near-field and far-field optical responses of the material.

The seminar will highlight strategies for fabricating plasmonic supercrystals, their unique optical characteristics, and selected examples of their applications.
