    The radiation properties and the electronic structure of hybrid composites based on suspension polystyrene (PS) and nanocrystals of BaZrO₃ (BZO) ( d < 50 nm) have been studied using luminescent spectroscopy and x-ray ...
  • Antuzevics, A.; Rogulis, U.; Fedotovs, A.; Popov, A.I. (Физика низких температур, 2018)
    The advances of EPR spectroscopy for the detection of activators as well as determining their local structure in the crystalline phase of glass ceramics is considered. The feasibility of d-element (Mn²⁺, Cu²⁺) and ...
  • Karbovnyk, I.; Bolesta, I.; Rovetskyi, I.; Lesivtsiv, V.; Shmygelsky, Ya.; Velgosh, S.; Popov, A.I. (Физика низких температур, 2016)
    Fresh and aged melt-grown or gas-phase grown CdI₂ crystals are studied by means of low-temperature photoluminescence spectroscopy. Noticeable transformations of emission spectra are observed after long-term aging. The ...

  • Mironova-Ulmane, N.; Skvortsova, V.; Popov, A.I. (Физика низких температур, 2016)
    We studied the optical absorption and luminescence of agate (SiO₂), topaz (Al₂[SiO₄](FOH)₂), beryl (Be₃ Al₂Si₆O₁₈), and prehnite (Ca₂Al(AlSi₃O₁₀)(OH)₂) doped with different concentrations of transition metal ions and exposed ...
  • Klym, H.; Ingram, A.; Shpotyuk, O.; Hadzaman, I.; Solntsev, V.; Hotra, O.; Popov, A.I. (Физика низких температур, 2016)
    Free volume and pore size distribution size in functional micro and macro-micro-modified Cu₀.₄Co₀.₄Ni₀.₄Mn₁.₈O₄ ceramics are characterized by positron annihilation lifetime spectroscopy in comparison with Hg-porosimetry ...
  • Lushchik, A.; Lushchik, Ch.; Vasil’chenko, E.; Popov, A.I. (Физика низких температур, 2018)
    Irradiation of alkali halide crystals creates pairs of Frenkel defects both in anion and cation sublattices. How-ever, the particular nonimpact creation mechanisms (related to the decay of different electronic excitations) ...
  • Kuzovkov, V.N.; Popov, A.I.; Kotomin, E.A.; Moskina, A.M.; Vasil'chenko, E.; Lushchik, A. (Физика низких температур, 2016)
    We analyzed carefully the experimental kinetics of the low-temperature diffusion-controlled F, H center recombination in a series of irradiated alkali halides and extracted the migration energies and pre-exponential ...
  • Kuzmin, A.; Pankratov, V.; Kalinko, A.; Kotlov, A.; Shirmane, L.; Popov, A.I. (Физика низких температур, 2016)
    Photoluminescence and excitation spectra of microcrystalline and nanocrystalline nickel tungstate (NiWO₄) were measured using UV-VUV synchrotron radiation source. The origin of the bands is interpreted using comparative ...
