Preparation of thin layers of sesquioxides (R2O3) with doped laser-active elements of rare earths
The so-called sesquioxides – such as Y2O3 or Lu2O3 – have high heat and radiation resistance. After doping with optically active ions, they represent a promising set of materials for scintillation use. These materials will be prepared as thin films on monocrystalline substrates.

Preparation of thin films of LuGAGG (Lu3–xGdxAl5–yGayO12) garnet with cerium doping and co-doping with various elements from the group of rare earths or transition metals
The so-called multi-component garnets can be successfully prepared with sol-gel methods for testing new compositions. In this work, we will focus on the unpublished co-doping with optically active ions.

 Thin layers of hexagonal aluminates to detect high energy radiation
Preparation and study of doping of hexagonal aluminates for optical applications (applied research)

 Passivating glass layers for applications in the semiconductor industry
Experimental verification of the passivation properties of glass precursors on semiconductor silicon components. Application of glass material is one of the important technological steps in the production of silicon semiconductors.
In cooperation with ABB Semiconductors

 ZnO doped nanoparticles doped with transition metals
Zinc oxide is a significant semiconductor of the AIIBVI semiconductor family. By doping with transition metals, so-called magnetic semiconductors, which have an application potential in spintronics, can be prepared.

 Use of transition metal doped BaTiO3 powder to improve magnetic resonance imaging
BaTiO3, an important ferroelectric, can be used in ever-improving imaging methods in medicine. The aim of the thesis is to test doping of this oxide for improvement of ferroelectric parameters in interaction with a high frequency magnetic field.

 Sol-gel preparation of transition metal oxides as pinning centers in YBaCuO superconductors
For the practical use of superconductors, the stability of their state is important in the presence of an external magnetic field. This parameter can be influenced by the presence of nanoparticles, such as transition metal oxides, to be prepared for this work.
