Current Themes of Research

  • Synthesis of oxides and non-oxides (nitrides and sulfides) (ceramic and soft chemistry methods)
  • Gas-solid reaction mechanisms (electrical prop., TPD/MS, DRIFTS in situ). Application to gas sensing
  • Passive optics: Sintering of infrared transparent ceramics by HP, HIP, SPS techniques
  • Active optics: Doped (RE or TM ions) (oxy)sulfides for phosphors, energy conversion, laser ceramics, optical refrigeration
  • Biomaterials: Elaboration and Porosity/Surface characterization
  • Photocatalytic properties of (oxy)nitrides (degradation of organic compounds)
