Spectrally tunable ADVANced nanosource for local SPECtroscopy – ADVANSPEC

Fast growth of Nanophotonics requires development of advanced integrated light nanosources for, e.g., nanospectroscopy and nanosensors. In this context, hybrid plasmonic nanosources (HPN), based on coupling between metal nanostructures and quantum nanoemitters, have given rise to intense research efforts. However, lake of control of spatial distribution of the nanoemitters makes limited the use of HPN. Advanspec aims at addressing this challenge. Intrinsic plasmonic modes of metal nanostructures will induce local surface functionalization through plasmon-mediated reduction of aryl diazonium salts in order to locally attach nanoemitters. The resulting anisotropic HPN will be polarization sensitive, permitting new multicolor emission properties and control. Three partners (L2n, LCBPT and ITODYS) will work for 4 years on 5 workpackages: surface chemistry, nanoplasmonics, HPN fabrication, HPN characterization, and use of the HPN for nanospectroscopy, as a first illustration of its potentials.
