Biography

Dr. Hemmer’s research program seeks to develop novel lanthanide-nanophosphors as multifunctional nanocarriers for near-infrared based bioimaging and energy conversion applications. Combining materials science, chemistry, physics and biological aspects, the three main areas of research are (i) the synthesis of lanthanide- nanophosphors with optimized near-infrared and upconversion emission, controlled size, crystalline phase and morphology and application-oriented surface modification, (ii) the implementation of the nanophosphors in biological systems and the assessment of nano-bio-interactions, and (iii) the design of novel optical materials for energy harvesting technologies.
