Materials synthesis and characterization:

• Functional nanomaterials for energy conversion.

• Metal nanoparticles for surface-enhanced Raman scattering and plasmonic applications

• Low dimensional materials for photonics and spintronics applications (2D materials, quantum dots,...).

• Conjugated organic molecules and macromolecules.

Study novel photophysical properties and devices:

• Tip-enhanced PL and Raman spectroscopy (TERS), nonlinear optical nano-imaging (N-NSOM).

TERS, a high spatial resolution (< 10 nm) of scanning probe microscope based on the chemical sensitivity of surface-enhanced Raman spectroscopy and plasmonic confinement of electromagnetic field near the metal tip apex. This technique provides insightful light-matter interaction phenomena down to atomic levels.

• Surface-enhanced Raman scattering, micro Raman, and PL imaging.

• Ultrafast microspectroscopy, magneto-optical spectroscopy (transient absorption, TR-SHG, TR-MOKE).

Study of ultrafast photo-physical phenomena in nanomaterials (spin, charge, charge transfer, and exciton dynamics).

• Single photon emitters for quantum information technology. Photonics quantum sensing.

• Novel device (optoelectronics, sensors, lasers,...) characterization.
