Final Report Summary - OPTNANO (Quantum optics in nanostructures)
Nanomaterials are intriguing structures for quantum optics. Their color depends on their size and shape; they are very selective in the wavelengths they absorb and emit. In this project, we developed a fundamental description of quantum optics in one-dimensional nanosystems. We used carbon nanotubes as model systems to understand quantum size effects, electron interaction in low-dimensional systems, and the response of nanostructures to changes in their local environment. The insight was then transferred to other low-dimensional materials like quantum wires and monolayers. We then proceeded to build new, complex nanohybrids that combined carbon nanotubes with functional molecules and metal nanoparticles. In proof of principles experiments we demonstrated the outstanding optical properties of the hybrid structures.
