Colloidal Nanoparticle Spectroscopy

Absorption, scattering, and emission spectroscopy or time-resolved emission spectroscopy - you name it!

I am an expert in absorption, scattering, and emission spectroscopy as well as time-resolved emission spectroscopy of colloidal nanoparticles. My main competence lies in the spectroscopy of lanthanide-activated nanocrystals which I complement with semiconductor nanoparticles such as quantum dots, Perovskites, or nanoplatelets as well as plasmonic nanoparticles such as Gold nanospheres or nanorods and, sometimes, carbon nanotubes. Besides the fundamental understanding of the optical properties of these particles and the interactions of hetero samples I take interest in such particles’ applications. Potential applications are lasers (nanoplatelets), nanothermometry (lanthanide nanocrystals), or catalysis (Gold nanorods). Recently, I started to involve such colloidal nanomaterials in dynamic self-assembly to better understand soft-matter physics at the nanoscale and to assemble novel photonic materials consisting of nanoparticles.
