Design, preparation, and modulation of spectroscopic properties of CaxZ1-xF2 compounds (where Z = Sr2+ and/or Ba2+ ions) co-doped with lanthanide ions and alkali metal ions
Auxillary supervisor: dr Adam Watras
Description:
The main goal of the PhD thesis is to design, synthesize, and investigate the spectroscopic properties of new nanosized systems of mixed fluoride compounds with a fluorite structure of the chemical formula X1-xZxF2 (where X, Z = Ca2+, Sr2+ or Ba2+ ions) doped and co-doped with lanthanide and alkaline ions (e.g. Li+ or Na+ ions) in the form of nanomaterials and nanoceramics. The structural and luminescent properties of the obtained materials will be compared to determine the best fit for the desired application.
The investigation will focus on potential applications of nanosized materials as optical sensor agents and nanoceramics as random laser materials. The most crucial aspect of this project is to investigate and explain how the composition and synthesis method of X1-xZxF2 mixed systems, doped and co-doped with rare-earth and alkaline ions, influences the clustering phenomenon.
