Design of novel functional optical materials based on fullerenes and atomic nano-clusters

Electronic structure, as well as photoexcitation and photoionization processes, of nanoclusters have been studied for more than several decades. During this period a number of important achievements have been made. For instance, the geometrical structure of mass-selected clusters has been studied in detail experimentally by means of the low-temperature photoelectron spectroscopy and theoretically by using the density functional theory (DFT). Among various types of atomic clusters, metal and carbon clusters have been of the main interest for studying.
