C7 – Novel hybrid systems based on liquid crystals and perovskite nanocrystals for enhanced nonlinear optical properties

The aim of NOA is to develop an understanding of nonlinear optics down to atomic scales. Along these lines the NOA consortium investigates novel hybrid systems with low and mixed dimensionality, which cannot be described via an effective medium approach, but allow to tailor nonlinear optical properties down to the molecular and atomic scales.

With this goal, project C7 will develop and offer new material platforms and hybrid structures with interesting largely unexplored nonlinear optical properties. These novel hybrid structures will combined 0D perovskite nanoparticles and 2D liquid crystalline thin films with metamaterials, metasurfaces and plasmonic nanostructured materials from the NOA consortium. The central nonlinear phenomena that will be investigated in C7 are second harmonic generation (SHG) as well as higher harmonics generation (HHG) and circular polarized light emission (CPL). It is anticipated that the molecular and materials components of the here designed hybrid materials will activate strong synergies and significantly enhance SHG and HHG efficiencies. It shall also be noted that the hybrid systems contain photoluminescent 0D components (molecules and nanocrystals) which will engage and potentially resonate with the light generated within the hybrid structures. The photoluminescence of these 0D components under the influence of SHG and HHG will be investigated.
