Łukasz Kłopotowski earned his Ph.D. cum laude at the Faculty of Physics, University of Warsaw in 2003. His thesis was devoted to studies of tunneling of excitons between semiconductor quantum wells. He then worked as a postdoc at Universidad Autónoma de Madrid, studying properties of exciton polaritons, quasiparticles emerging under strong light-matter coupling. Since 2004 he works at the Institute of Physics, Polish Academy of Science. Initially, he studied self-assembled quantum dots, investigating the possibility of electrical tuning of their spin state. Recently, his work is centered around tailoring the optical properties of colloidal nanostructures with a view of applications in optoelectronics, photovoltaics, and nanomedicine.

Currently, Łukasz is leading a project on physics and applications of ternary I-III-VI nanocrystals - cadmium-free, less toxic alternatives to well-known cadmium chalcogenide nanocrystals. The project is aimed at revealing the mechanism of light emission in these nanostructures and applying them to photovoltaic devices. Łukasz is also leading investigations of rare-earth doped nanoparticles. The goal of this research is to tailor the up-conversion properties of these nanoparticles by forming hybrids with semiconducting quantum dots or plasmonic nanostructures.
