PhD: 2012 Adam Mickiewicz University, title: “Synthesis and physicochemical studies of nanophosphors based on modified zinc oxide and rare earths borates”.
MSc: 2007 Adam Mickiewicz University, title: “The luminescence characteristics of systems generating reactive oxygen species in the presence of lanthanide ions and tetracycline”.
Research topics
- Synthesis of submicro- and nanophosphors including modified multifunctional luminescent – magnetic inorganic materials based on borates, vanadates and fluorides doped with lanthanides ions, using solvo/hydrothermal, co-precipitation or sol-gel Pechini methods, which exhibit visible emission under VUV, UV or IR radiation.
- Physicochemical analysis of compounds synthesized: spectroscopic analysis based on luminescence spectra (in the range from VUV to IR region) and lifetimes, structural and morphological characterization with the use of XRD, FT-IR, SEM, TEM, TGA, BET, ICP-OES, XPS methods, calculation and analysis the Judd-Ofelt parameters, quantum efficiency and chromaticity coordinates.
Projects
“Ecological celulose fibers and paper modified by micro- and nanoluminophors activated by ultraviolet and infrared radiation” (LIDER/39/0141/L-9/NCBR/2018, The National Centre for Research and Development)
Main goal of this project is:
- to obtain cellulose fibres and paper – ecological materials, which structure will be modified with luminescent modifiers, ML, synthesized,
- to synthesize printer inks modified with ML and to get luminescence overprints on paper, and:
- synthesis of ML – inorganic micro- and nanophosphors with suitably designed spectroscopic properties, based on rare earth elements, which emit visible light with desired colour, under dual-mode excitation of ultraviolet UV or/and infrared radiation IR.
