Fluorescence properties of colloidal semiconductor quantum wells

After an introduction about the general work of the group Nanostructures and Optics at INSP, I will present the methods which we developed for characterizing the orientation and optical dipole contributions to the fluorescence of a single nano-emitter. These strategies were applied to a variety of semiconductor colloidal nanostructures : nanocrystals, nanorods, nanoplatelets (quantum wells)... In our most recent work, we considered self-assembled chains of nanoplatelets and evidenced various effects of coupling between platelets.
