Abstract

Transition-metal carbonyl clusters form an attractive class of materials to nonlinear optics, not only for the fundamental aspects of photon-matter interaction, but also due to their potential photonics applications. Organometallic complexes can show large differences in the eletronegativities of the metal and ligand atoms, which can introduce large polarities. Materials with high two-photon absorption coefficient, such as organometallic compounds, have been investigated for a range of applications, including multiphoton microscopy, optical limiting and optical storage.¹
