Research areas

Prof. Wondraczek's research activities span all areas of experimental glass science with particular focus on the exploration and development of new glass and glass ceramic compositions and surface modification techniques. His main thrusts are the optical and mechanical properties of multi-component oxide, oxynitride and oxyhalide materials. He is exploring structure-property relations with the ultimate objective of providing topology-based tools for the description of non-crystalline solids. Research interests include:

  • glasses for applications in optics and energy technologies
  • photoluminescence, magneto-optical materials, and fiber optics
  • relaxation processes in complex systems

Teaching fields

Prof. Wondraczek teaches interdisciplinary materials science where he connects materials engineering, physics and chemistry. He gives courses in:

  • solid state kinetics and thermodynamics
  • composite and nanocomposite materials
  • glasses and optical materials

Research methods

The laboratories led by Prof. Wondraczek offer state-of-the-art equipment for the fabrication and experimental characterization of glasses and other optical materials, including:

  • extensive glass melting capabilities
  • high resolution static and dynamic luminescence spectroscopy, Raman and FTIR spectroscopy
  • advanced high-temperature processing (< 2200 °C), including nitridation and hydration
  • extensive thermoanalytics, including STA-MS, DSC, DTA, TGA, HP-TGA, DDSC
  • extensive nanomechanical testing, including indentation, nano-scratching, nano-bending, lateral nanotesting and tribological analyses
