Laboratory of Crystal Spectroscopy
(LCS)

Department of Physics of Crystals

Institute of Physics
the National Academy of Sciences of Ukraine
     The Laboratory of Crystal Spectroscopy (LCS), headed by Gertruda Klimusheva, was established at the Institute of Physics in 1978 at the initiative of the academician A. F. Prikhotko, who was the head of the Department of Physics of Crystals at that time. The main area of LCS researches was the solid state physics: spectroscopy and X-ray analysis of molecular crystals for fundamental study of exciton energy zones in new organic compounds.
     From 80-th years of the twenty century Prof. G. Klimusheva has initiated the research of physical properties of liquid crystals.

Main areas of researches:

  • Study of spectral and nonlinear optical properties of the pure and impurity cholesteric liquid crystals, which possess high sensitiveness to external influences: e.g. mechanical, thermal, electrical and magnetic fields. The optical bistability and dynamic holography gratings recording in dye doped cholesteric liquid crystals were obtained for the first time in LCS.

  • Study of spectral, nonlinear optical, electrical properties of liquid crystals of a nontraditional class — ionic liquid crystals (ILC) of the metal alkanoates. The metal-alkanoates can form both lyotropic and thermotropic ionic liquid crystals as well as isotropic or anisotropic glasses. The ionic liquid crystals can be used as optical matrices for doping by organic and inorganic admixture and also for the synthesis of semiconductor and metallic nanoparticles (NPs), whose shape and size can be controlled in the matrix.

  • Study of nonlinear optical mechanisms in ionic liquid crystals and mesomorphic glasses of metal alkanoates, as well as in their composites with organic and inorganic substances, semiconductor and metallic nanoparticles, that are perspective for employing in opto-electronic and photonic devices.

  • X-ray analysis of structure and polymorphism of new materials that have mesomorphic phases.

  • Theoretical and experimental research of dissipative solitons.

  • Optical information processing and signal processing based on the dynamic holographic transformation of laser beams in materials with local, nonlocal or inertial nonlinear response.
