Dr. Nathalie Kunkel
Liebig Group: Development of novel rare earth doped materials for optical applications
Academic Career and Research Areas
Dr. Nathalie Kunkel (*1986) is interested in the development of novel rare earth doped materials for optical applications. Rare earth doped materials play an important role in different applications, such as solid state lighting, plasma screens, sensors, lasers, filters and in quantum information technology. In our group hydrides, mixed anionic hydride halides and borohydrides are studied. Next to X-ray and neutron diffraction, our main characterization methods are photoluminescence and thermoluminescence spectroscopy. During our investigations a detailed understanding of the relations between structure and optical properties is developed.
Dr. Nathalie Kunkel studied chemistry at the Saarland University and obtained her diploma in 2010 (degree with honours). After completing her PhD in 2014 (summa cum laude) and a short postdoctoral stay at Leipzig University, she moved to the IRCP, Chimie-ParisTech (Materials for Photonics and Opto-Electronics), Paris, France as a postdoctoral fellow. There she worked mainly in the fields of high resolution laser spectroscopy and materials for quantum information technology (funded by the DFG). In October 2016 she started to establish a junior research group at the Technical University of Munich, supported by a Liebig fellowship of the Fonds der Chemischen Industrie.
