The project for the postdoctoral fellow aims at developing nanostructured hybrid inorganic nanohelices/gold nanoparticles (GNPs) as novel devices which show new enhanced chiro-photonic properties. To do so, a four-step strategy is proposed. 1) high yield synthesis (scale-up) of well-calibrated silica nanohelices by bottom up strategy with controllable helical pitches. 2) in-situ synthesis of GNPs using these nanohelices as templates, following the chiral organization of the helix giving rise to enhanced surface plasmon and/or optical chirality properties in one particular direction; 3) their controlled assembly to enhance the properties and create valuable devices; 4) optical characterization of these hierarchical structures. The optimization of this step is crucial as it has to be adapted to the 3D structure, devoid of artefacts (LD, LB etc…) due to the organization. These highly innovated nanostructures will then be optimized for a technological transfer to applied science, and particularly for the nano-photonic applications.
For this study, the candidate having following expertise is needed: organic synthesis, sol-gel chemistry, electron microscopy, chiroptical techniques (CD, CPL) spectroscopy (UV, FT-IR), and optical spectroscopy. A good level of scientific English is required. Candidates who obtained their thesis from Bordeaux or who previously held a post-doc position in the CBMN will not be considered.
