  • synthesis of powder reference samples of chalcogenide compound semiconductors by solid state reaction (fig. 1)
  • synthesis of chalcogenide nanoparticles by wet-chemical routes (fig.2)
  • synthesis of hybrid-perovskites
  • chemical analysis of the synthesized material by WDX spectroscopy using an electron microprobe system
    (Freie Universitaet Berlin, Institute of Geological Sciences)
  • basic structural analysis of the synthesized materials by X-ray powder diffraction
