LAnthanide doped NAnomaterials SYnthesis and LUMinescence group

LaNaSyLum ia a research team lead by dr hab. Tomasz Grzyb and a part of Department of Rare Earths at Adam Mickiewicz Univeristy in Poznań, Poland.

We are focused on the synthesis and characterization of luminescent nanomaterials, doped with lanthanide ions which determine their properties. The main topic of our research is the up-conversion phenomenon, i.e. conversion of near-infrared light to higher energetic one, e.g. visible. We are developing nanoparticles, including core@shell, SiO2-coated, or surface-modified for energy-conversion, sensors, biomedical and optoelectronic applications. We are also interested in basic research, such as studies under mechanisms responsible for the formation of our products or their spectroscopic properties. Nowadays, our main research topic is up-conversion from above 1000 nm which might be especially interesting for solar energy conversion.
