“We design, produce and characterize materials containing rare earth elements and not only”

RARE EARTH COMPOUNDS

Our main scientific area is related to the design, synthesis and physicochemical characterization of nanoparticles based on rare earth inorganic matrices doped with lanthanide ions. However, this is not all, we are also able to prepare and characterize the macromolecules of lanthanide ions’ complexes and systems showing chemi- and electroluminescence phenomena.

SYNTHESIS

We are experienced in the synthesis of down-converting/down-shifting and up-converting nanoparticles including nanoparticles activated under radiation from the second (1000-1350 nm) and third biological window (1550 -1870 nm), as well as dual-mode nanoparticles activated under UV (200-450 nm) and NIR radiation (800-1000 nm) used in many areas, e.g. as anti-counterfeiting systems. We work also on nanoparticles surface modification with organic molecules for biocompatibility improvement and preparation and stabilization of luminescent nanocolloids. Finally, we can design and synthesise bifunctional luminescent-plasmonic and luminescent-magnetic nanoparticles.
Our laboratory is well-equipped, which allows for various methods of synthesis, including hydro/solvothermal method (high-pressure and high-temperature autoclaves), precipitation in high-boiling solvents (Schlenk line), sol-gel Pechini method (high-temperature and tube furnaces), co-precipitation and micro-emulsion ways of materials production.

SPECTROSCOPY AND STRUCTURE

The Department of Rare Earths has a laboratory equipped with advanced lasers systems and other devices for spectroscopic/optical measurements, which enable to characterize materials based on absorption, excitation and emission spectra (200- 1700 nm), luminescence lifetimes and emission quantum yields. In our laboratories, there are also possible experiments related to the high-pressure and temperature-dependent luminescence and optical detection of phase transitions under pressure. The measurements can be conducted both at room and liquid nitrogen temperature.
Our skills enable us to provide studies related to the structural characterization of the materials synthesized with the use of X-ray diffractions, IR – absorption spectra, DLS, potential Zeta techniques and also SEM and TEM images.

APPLICATIONS

We produce nanoparticles applicable in biomedicine and bioimaging, temperature and pressure sensing. Other fields and possible applications include anti-counterfeit markers based on magnetic/luminescent cellulose microfibers, paper and ink formation; light-emitting diodes – LEDs production, plasmonic surface enhancement and solar-cells, etc.
