Hybrid nanoobjects formed by two or more different materials are among the most promising and versatile nanosystems. They are still little exploited and their development presents important fundamental challenges. This project focuses on the design and synthesis of novel metal-semiconductor nano-hybrids, on characterizing them and investigating their linear and nonlinear optical responses at the single nanoobject level, and on modeling their new properties. Because of particle to particle structural fluctuations, investigation of a single identified particle is required to correlate its geometry and structure to its properties and to compare them with theoretical models. This will be made possible by the complementary and unique expertise of the four partners on synthesis, characterization, optical study, and modeling of nanoparticles. The acquired new knowledge will permit to improve their properties and, in particular, to bring closer application of nano-hybrids as optical biolabels.
