Laser Spectroscopy and Modification of Materials

Research Directions

Yu.S. Tver'yanovich. "How to Make Inorganic Glass Plastic?"

Inorganic glasses are formed by directional and short-range covalent bonds. Therefore, glasses do not have plasticity, they are brittle. Polymer organic glasses are also formed by covalent bonds, but they are plastic and not so brittle. The reason is the large number of Van der Waals bonds they have. This means that in inorganic glasses, to increase plasticity, it is necessary to create Van der Waals bonds. These include metallophilic interactions that occur, for example, between silver atoms. Therefore, inorganic glasses with a high content of silver compounds, a multiple increase in their plasticity, the ability to relax mechanical stresses, the effect of glass composition on their structure and other performance properties are studied.

 "Obtaining Green Hydrogen from Natural Gas"

When laser plasma acts on natural gas, hydrogen and a solid carbon material (tholins) are obtained. There are no greenhouse gas emissions. The method involves the production of hydrogen fuel by small-sized units directly at the consumer. This eliminates the need for transportation and storage of hydrogen, and the operation of the existing gas transportation system continues. Research objectives: optimize the parameters and mode of laser radiation, study the mechanism of natural gas decomposition using femtosecond spectroscopy, develop a method for obtaining carbon materials with high added value (graphene, nanodiamonds, etc.) from tholins.

A.V. Povolotsky. "Laser Modification of Materials"

Methods for laser modification of glasses of various compositions are being developed in order to locally change the composition and/or structure. The kinetics and dynamics of the formation of laser-induced processes are studied: generation of hot electrons, migration of free electrons, migration of alkali ions. Methods for the formation of color centers, waveguides, and diffraction gratings in the volume of glasses are being developed. "Development of Molecular Plasmonic Structures for Biomedical Applications"

Nanostructures with the following functional properties are being developed: singlet oxygen generation for photodynamic therapy, photoinduced heating for photothermal therapy, photoinduced reactions for chemotherapy, luminescence thermometry and surface plasmon-enhanced Raman scattering. The possibility of combining the functional properties of the components of hybrid nanostructures in order to create universal drugs for controlled complex therapy is being studied.

"Development of New Crystalline Phosphors Activated with REI"

Study of structural features using vibrational spectroscopy (IR and Raman); measurement of absorption spectra and determination of the optical width of the band gap; study of the emission efficiency of phosphors based on steady-state luminescence spectroscopy and time-resolved spectroscopy; study of nonlinear optical properties of polycrystalline samples based on the efficiency of second harmonic generation; development of phosphors with a "pure" color of radiation for modern displays.

A.S. Mereschenko. "Metal-organic framework structures of lanthanides"

Research is underway on luminescent metal-organic framework structures of lanthanides that exhibit the antenna effect (MOF). They consist of metal ions (or clusters) linked together by organic polydentate bridging ligands. The use of different combinations of metals and ligands allows obtaining materials with different properties. Lanthanide compounds are phosphors. However, lanthanide ions themselves absorb light very poorly, but they can be combined with an "antenna" using MOF — an organic compound that absorbs light well and transfers its energy to the lanthanide. Such "centaurs" can be used to create luminescent paints, security elements of documents, elements of gadget screens, sensors and luminescent sensors.

"Inorganic fluoride nanoparticles of lanthanides for biovisualization"

In photobiology and biomedicine, nanoparticles based on NaYF4 with the addition of other rare earth ions are widely used due to the low toxicity of the material and its ability to penetrate tissues. Thus, particles with gadolinium are already used to create contrast agents during magnetic resonance imaging, nanoparticles with europium - as luminescent markers of various diseases. The research group conducts studies of the structure, optical properties and morphology of fluoride nanoparticles of lanthanides, which have pronounced luminescence and paramagnetic properties - a new magnetic-luminescent nanomaterial that makes it possible to carry out two types of diagnostics at once - using light and a magnetic field, which significantly increases the efficiency of disease detection. In cooperation with biologists, studies are conducted on the cellular toxicity of the resulting materials, luminescent microscopy of cells. Research is planned on MRI diagnostics using synthesized nanoparticles as a contrast.

A.S. Tver'yanovich. "Research and development of chalcogenide glassy semiconductors"

New thin-film materials are being developed for use as PCM (phase-change materials for memory elements); thin-film materials with high optical nonlinearity; chalcogenide glasses with atypical optical nonlinearity (second-order nonlinearity); chalcogenide glasses containing rare-earth ions, as active optical materials for IR optics, including fiber optics. The effect of high pressure on chalcogenide glasses is studied from the point of view of the possibility of controlling their functional properties.

M.S. Popov. "Development of new composite materials for application in enzyme-free sensing"

Controlled laser-induced synthesis of composite materials based on transition and noble metals to create sensors with high electrocatalytic activity for enzyme-free determination of a number of biologically important analytes, including glucose and dopamine. Search for solutions for obtaining materials with high sensitivity to such a difficult-to-determine hydrophobic metabolite as adrenaline.

"Study of photophysical and spectral properties of fluorescent proteins based on rhodopsins for optogenetic applications"

Measuring the spectral and photophysical characteristics of new rhodopsin variants used in optogenetics and studying their effect on the quantum yield and potential dependence of fluorescence using spectral methods, including high-temporal-resolution spectroscopy.

"Study of photophysical and spectral properties of fluorescent dyes based on pyranochromenes for various applications"

Measuring absorption and luminescence spectra, determining luminescence quantum yields and studying luminescence mechanisms using up-conversion and difference absorption spectroscopy methods of a series of pyranochromenes for applications in chemosensors, biosensors and biological imaging.
