The next generation of optoelectronic applications like stimuli-responsive sensors, functional displays or nanophotonic circuits demands a basic understanding of lightmatter interactions on the nanoscale. Top-down fabrication has been employed in the past to demonstrate coherent energy transfer in functional nanostructures, yet these fabrication methods are problematic due to their limited scalability and high costs as well as the high optical losses. This work adapted physical principles like radiation properties of metallic nanoantennas and Bragg diffraction in periodic nanostructures and realized these concepts using bottom-up self-assembly methods based on colloidal chemistry. With this approach, single plasmonic nanoparticles and semiconductor quantum emitters were co-assembled into complex structures. This work took the colloidal concept from plasmonics and introduced quantum dots in order to characterize the radiative and non-radiative decay processes as well as the arising light-matter interactions. Due to electromagnetic coupling between the components, hybridized modes were detected instead of the single particle resonances observed in the isolated case. It was furthermore shown that these colloidal building blocks can be assembled into functional optical grids on a large scale using template-assisted self-assembly. Thus, this work established spectroscopic principles for self-assembled colloidal building blocks that can be integrated in parallelized processes in the future.
