Research

I am working on the exploratory synthesis of chalcophosphate/germinates/stannates. The main interest is discovery of new nonlinear optic and crystal-glass phase transition materials in this system.

Master degree work was focused on the synthesis of new colloidal nanostructure of layered ferroelectric oxide, inorganic/organic nanohybrid and layered perovskite fluorooxides.

Representative work during M.S. degree

1. Neutron diffraction and X-ray absorption spectroscopic analyses for lithiated Aurivillius-type layered perovskite oxide Li2Bi4Ti3O12. J. Phys. Chem. B
2. Macromolecular nanoplatelet of Aurivillius-type layered perovskite oxide, Bi4Ti3O12. Chem. Mater. (Communication)
3. Transformation of Dion-Jacobson-type layered oxyfluorides into new anion-deficient pyrochlore-type oxides. ASrNb2O6.5. (A=Li, Na) J. Mater. Chem.

Main techniques:

Solving solid state structure using single crystal XRD and powder XRD or ND (neutron diffraction) by Rietveld method. X-ray absorption spectroscopy technique (EXAFS, XANES). Small angel XRD spectroscopy technique (SAXS), SEM, TEM. Flux synthesis of metal chalcogenides. High temperature and sol-gel synthesis of metal oxide.
