AbstractThis issue contains the Proceedings of the 10th International Conference on the Optics of Excitons in Confined Systems. OECS‐10 is the tenth of a very successful series of conferences that started in 1987 in Rome, Italy, and has been addressed to scientists who lead fundamental and applied research on the optical properties of excitons in novel condensed‐matter nanostructures. The 2007 meeting brought together a large representative of the world leading actors in this domain, with the aim of stimulating the exchange of ideas, promoting international collaborations, and coordinating research on the newest exciton‐related issues such as quantum information science and exciton quantum‐collective phenomena. The main topics treated were: heterostructures of low dimensionality, quantum wells, quantum wires and quantum dots, polaritons, quantum optics with excitons and polaritons, quantum coherence and quantum‐phase manipulation, Bose–Einstein condensation and other collective phenomena, excitons in novel materials.The success of the conference has also been possible thanks to the invaluable help of Giovanna Martino, Giuseppe Pistone, and Omar Di Stefano, who undertook all the local organization tasks. Finally, we would like to acknowledge the financial andtechnical support ofEcole Polytechnique Federale de Lausanne (EPFL)Fondazione Umberto Bonino & Maria Sofia PulejoDipartimento di Fisica della Materia e Tecnologie Fisiche Avanzate, Universita' degli Studi di MessinaDottorato di Ricerca in Tecnologie Avanzate per l'Optoelettronica e la Fotonica e Modellizzazione ElettromagneticaThe success of this event has motivated the continuation of the series of OECS conferences. The 11th International Conference on the Optics of Excitons in Confined Systems will be organized in Spain in September 2009 and will be chaired by Prof. Luis Viña.Messina, Patti, September 2007
