Light-harvesting complexes (LHC) are nanoscale structures found in photosynthetic organisms. They are ring-like structures used to efficiently absorb light and transport quantum excitations to induce chemical processes. Constructing artificial complexes, that mimic these natural phenomena, allow to develop new functional materials for quantum photonics. In this work, we introduce LHC based on silicon-vacancy color-centers in diamond coupled to gold nanostructures and study their photophysics.

Keywords: Light-harvesting complexes; Silicon-vacancy color-centers; Gold nanostructures
