Emerging materials for plasmonics

Abstract : For twenty years, the noble metal nanoparticles present an increasing interest due to their varied and complex optical properties. These properties are mainly governed by collective oscillations of conduction electrons called "plasmons". In particular, the excitation of the plasmon resonance by optical fields leads to a local exaltation of the electromagnetic field close to the nanoparticle. Such very intense nanosource paves the way for numerous applications: controlling, manipulating and amplifying the light at the nanoscale. In this talk, I will present our latest results obtained on new materials for plasmonics. Such materials have been chosen because of their price, abundance on earth and optical properties. The first part will be dedicated to new materials allowing to dress plasmon resonance in the UV region. Then I will present materials with plasmon resonances situated in the visible and NIR regions. Finally, the last part of my talk will be dedicated to Mie resonators. Such resonators are really promising for exalted scattering based applications or structural colors.
