| Summary: | The optical properties of multi-component metal nanostructures (or nanoalloys) are the subject of an intense and rapidly growing experimental and theoretical activity. In this perspective article, we first provide a survey of the most recent developments in the field, concerning both theoretical methods, especially at the first-principles level, and novel results, distinguishing for the convenience of presentation the sub-field of monolayer-protected multi-component metal clusters from the other alloy nanosystems. We then discuss a few general concepts which can be drawn from this survey, and offer a few suggestions on the most promising directions for future research. We hope that making the point in this fast developing field will provide a framework and a perspective useful to trigger future studies and advancements.

| Bibliography: | Giovanni Barcaro, PhD in Chemistry in 2007, works as a researcher at the Pisa Unit of the Institute of Chemical and Physical Processes (IPCF) of the Italian National Research Council (CNR). During the last years, his research interests have been focused on the theoretical and computational investigation of the structural, optical, magnetic and catalytic properties of hybrid systems, ranging from pure and alloyed metallic nanoclusters in various environments (gas-phase, on insulating surfaces, covered by organic ligands) to ultrathin oxides grown on metallic surfaces. Mauro Stener graduated cum laude in chemistry in March 1992 at Trieste University (Italy). In 1995 he completed his PhD in Theoretical Chemistry at University of Trieste with a dissertation on the application of the Density Functional Theory to excited states of atoms and molecules. Since 2006 he is Associate Professor of Physical Chemistry. The main interests of M. Stener consist in the development of new DFT and TDDFT methods to describe photoionization and photoabsorption processes. He is author of 150 papers. Luca Sementa received his PhD in Chemistry from the Federico II University of Naples in 2009. During the same year he was guest researcher at the chemistry department of the Leiden University and since 2010 he is post-doc researcher at the Italian National Research Council in Pisa. His current research is focused on the theoretical description of the electromagnetic response of nanostructures, computational heterogeneous catalysis and the application of many-body techniques to describing the electronic structure of nanosystems. Alessandro Fortunelli is Senior Researcher at National Research Council (CNR) in Pisa (Italy), which he joined in 1984 after obtaining his degree in Chemistry at Pisa University and Scuola Normale Superiore (where he also obtained his PhD in Chemistry). He is presently Visiting Associate at Caltech, Pasadena (USA). His research interests focus on structural, optical, catalytic and magnetic properties of pure and alloyed metal nanoclusters, oxide-on-metal ultrathin films, and computational materials science at large. He is author of more than 190 articles in peer-reviewed journals. ObjectType-Article-1 SourceType-Scholarly Journals-1 ObjectType-Feature-2 content type line 23 |
