Various oxides (ZrO2, HfO2, ZnO, SrAl2O4 etc.) doped with rare earth (RE) ions are studied. Optical properties are of main interest; however, laboratory staff is trained to perform other tasks: electron microscopy (SEM, TEM), sample preparation (Plasma Electrolytic Oxidation (PEO), various synthesis methods in a well-equipped chemical lab), as well as other material characterization (EDX, XRF, XRD).

Luminescence properties of ZnO in its various forms (monocrystals, nanopowders, ceramics and coatings) are studied. PEO coating research as well as dopant implementation development with the aim to improve and functionalize optical properties of coating. New PEO structures are produced with their characteristic properties, technologies for practical application of such coatings are developed.

Up-conversion luminescence studies are performed on RE doped ZrO2 and various ceramics.

Thermostimulated luminescence (TSL) methods are developed and applied. Unique developed setup allows the measurement of spectral distribution dependence on temperature. Various heating regimes allow defining the thermal activation energies of traps.
