NanOOptics & Spectroscopy (NOOS)

Activité scientifique

The NOOS team focus on three main activities:

• Nanographene light sources: We study the electronic and optical properties of nano-graphene objects (quantum dots and ribbons) with perfectly controlled structures by chemistry. We are interested in tailoring their quantum properties and integrating these objects with other 2D materials.
• Hybrid perovskites: We investigate the optical properties of colloidal nanoparticles and defects of hybrid perovskites.
• Optical levitation of nanoparticles: We take advantage of the excellent decoupling to the environment provided by optical levitation for fundamental studies of quantum macroscopic effects, and nanothermodynamics and for developing innovative sensors.
