The aim of this study is to capitalize on the richness of the crystalline, magnetic and electronic structures and photocatalytic properties of W-based oxides by investigating the Fe-W-O system. It is proposed to focus on Fe₂WO₆ as it crystallizes in three different structures exhibiting different transport and magnetic properties. It is of interest to study the thermodynamic conditions in this area of the ternary diagram Fe-W-O to monitor and optimize precise composition and synthesis conditions. Structures and microstructures will be studied by suitable diffraction methods and microscopies. Compounds will be characterized by measuring their magnetic and electrical properties; those with suitable bandgap will also be tested for photocatalytic or photoelectrochemical properties relevant to catalytic degradation of organic pollutants, water splitting or photovoltaic cells.

Transparent ceramics can compete with single crystalline materials not only in the stage of research and development but also in the final application. The thesis will be focused on the synthesis of oxide ceramics applicable in the laser or LED field, or utilizable at the detection of ionizing radiation. Spark plasma sintering (SPS) or vacuum sintering will be used for the processing of precursor powders whose optimal crystallinity and microstructure will be also the task of the thesis.
