The work was conducted under the auspices of the Russian Science Foundation; the project Synthesis and research of a new class of nanocomposite ceramics with degenerate dielectric constant for optoplasmonic applications is headed by Professor Sergey Kharintsev (KFU s Institute of Physics).
Professor Kharintsev, the first co-author, comments, Under the influence of light, collective oscillations of electrons can be excited in metallic nanostructures, and as a result the electric field in the vicinity of the nanostructures strongly increases. The field of physics that studies the effects of generation and propagation of such electromagnetic excitations is called plasmonics. Its most striking achievements include optical visualization of single molecules and diagnostics of their vibrations with a spatial resolution of 0.16 nm (for example, the size of a water molecule is 0.3 nm). In practice, the achievements of plasmonics are widely used in the development of highly sensi
