Chalcogenide clusters in combination with various different ligands offer a large variety of structural and physical properties. In particular, their nonlinear optical response can be tuned, e.g., enabling second harmonic generation by varying the compositions and constituents of cluster cores and ligands. Modifying the core primarily influences the band gap energy, whereas changing the ligand influences the anharmonicity of the electronic potential and thus the efficiency of nonlinear processes.
