Main Research Focus

The main research group focus are on new inorganic materials, nano-structures and functional surfaces including synthesis, characterization and related technology development. Synthesis, characterization and applications of silica and upconverting nanocrystals (such as NaYF4: doped with rare-earth elements) and its composites, surface modification and their application for biomedical imaging. Also, sol-gel synthesis and investigations of inorganic-organic hybrid materials, advanced nano-materials (luminescent and optical materials, biomaterials as biocompatible ceramic and bioactive surfaces for biotechnology application.); nanostructural materials; surfaces and interfaces. Our research interests also include investigation of functional materials surface and coatings; development of aerosol-pyrolysis technique for oxide films. Additionally research is focused on the relation between molecular structure of the precursors (and the synthesis parameters that determine these properties) and the structural and macroscopic properties of the optical materials or biomaterials.
