**Self-assembly and optical properties of gold nanoparticle superlattices for
surface-enhanced Raman spectroscopy**
Mathias Charconnet

Due to their remarkable ability to confine light to the nanoscale, plasmonic
nanostructures are ideal platforms for ultrasensitive spectroscopy techniques,
such as surface-enhanced Raman scattering (SERS) spectroscopy. SERS has
emerged as a technique of choice for the monitoring of low concentrations of
chemicals and biological markers. Therefore, the fabrication of new optimized
plasmonic substrates for SERS is essential for the detection of even lower
concentrations of molecules. High and efficient SERS signals typically demands
a match between the plasmon resonance wavelength and the Raman laser
excitation wavelength. Plasmon resonances can be tailored through the
nanostructure's shape or material. Particularly, in periodically arranged
nanoparticles, i.e. plasmonic superlattices, the plasmon resonance can be
tuned through changes in the lattice period. In this context, the overall
goal of this thesis is to fabricate and study the plasmonic properties of
highly regular gold nanoparticle superlattices made through self-assembly,
with the aim of optimizing their SERS performance.
