Hartmut Yersin

Professor Hartmut Yersin is a leading researcher in the field of photophysics and materials science at the Institute of Physical Chemistry, University of Regensburg. His work focuses on transition metal complexes, particularly for OLED applications, with significant contributions to understanding thermally activated delayed fluorescence (TADF) and triplet harvesting mechanisms.

His research interests center around developing efficient luminescent materials, particularly copper(I) and platinum(II) complexes for organic light-emitting diodes. Professor Yersin has pioneered work on thermally activated delayed fluorescence, triplet harvesting, and singlet harvesting mechanisms that significantly improve OLED efficiency. His research group investigates how molecular structure affects photophysical properties, with particular attention to spin-orbit coupling, energy gap laws, and emission decay dynamics.

His recent publications reveal a strong trend toward developing cost-effective copper-based emitters as alternatives to expensive iridium complexes, with a focus on achieving high quantum yields and short emission decay times. His work bridges fundamental photophysics with practical device applications, making significant contributions to the field of organic electronics.

Professor Yersin has mentored numerous doctoral students and researchers who have gone on to contribute significantly to the field of photophysics and materials science. His research has been supported by collaborations with institutions worldwide, including groups in Australia, Austria, Belgium, Brazil, China, France, and Japan.
