• Contact : Emmanuelle DELEPORTE, Emmanuelle.Deleporte ens-paris-saclay.fr
• Topics :
- Study of the intrinsic properties of halide hybrid perovskites, in particular two-dimensional Ruddlesden-Popper perovskites, in the framework of photovoltaic applications and light-emitting components.
- Study of the light-matter interaction in photonic microcavities containing hybrid perovskites, in particular study of polaritons.
- Molecular engineering and functionalization of halide hybrid perovskites.
- Ultrafast exciton and charge carrier dynamics in colloidal perovskite nanostructures.
- Detection of the early steps of the nucleation of perovskites.
• Experimental means / theoretical tools :
- Materials :
Colloidal synthesis of 2D and 3D halide perovskites
Growth of single crystals of halide perovskites
Deposition in thin layers by spin-coating.
Micro and nano-crystals production in a microfluidic system - Optical studies :
Steady state optical spectroscopy (absorption, reflectivity, photoluminescence).
Time-resolved (TCSPC) and spatially-resolved photoluminescence in the visible, as a function of temperature (10K – 300K).
Ultrafast pump-probe spectroscopy (femtosecond transient absorption spectroscopy) with UV-vis-NIR excitation.
Full-field fluorescence lifetime imaging (FLIM)
