  • Afterglow suppression in CsI crystal by Eu²⁺ doping 
    Shiran, N.; Gektin, A.; Vasyukov, S.; Tkachenko, S.; Sofronov, D. (Functional Materials, 2011)
  • Defects related luminescence in yttrium-aluminum garnet crystals 
    Shiran, N.; Gektin, A.; Hubenko, K.; Nesterkina, V.; Arhipov, P.; Tkachenko, S.; Sidletskiy, O. (Functional Materials, 2016)
    he estimation of the fundamental limits of scintillation efficiency requires the analysis not only of electron channel of the energy transformation but also of the role of interplay between electron and phonon channels. ...
  • Energy transfer in co-doped NaI:(Tl,Eu) crystals 
    Gridin, S.; Vasyukov, S.; Shiran, N.; Gektin, A. (Functional Materials, 2014)
    The energy transfer mechanism in Eu doped and Tl, Eu co-doped NaI crystals is discussed. The self-trapped exciton emission band overlaps stronger with Eu²⁺ excitation bands rather that with Tl⁺. This suggests that transfer ...
  • New red phosphor: Ca₀.₆₅Eu₀.₃₅F₂.₃₅ single сrystal 
    Shimamura, K.; Shiran, N.; Gektin, A.; Voronova, V.; Nesterkina, V.; Ichinose, N.; Villora, E.; Shishido, T. (Functional Materials, 2004)
    The first observation of absorption, red-orange luminescence, and decay kinetics of Ca₀.₆₅Eu₀.₃₅F₂.₃₅ single crystal is reported. The emission spectrum of excited directly in absorption bands consists of narrow bands at ...
  • Optical and scintillation properties of CsI:In crystals 
    Gridin, S.; Shiran, N.; Moszynski, M.; Belsky, A.; Syntfeld-Kazuch, A.; Tarasov, V.; Gektin, A. (Functional Materials, 2013)
    The work is dedicated to study of optical and scintillation properties of CsI:In crystals. Using the Bridgeman method a concentration row of CsI:In single crystals was grown with the dopant content from 10⁻⁴ to 10⁻¹ ...
  • Radiation damage of CsI:Eu crystals 
    Gektin, A.; Vasyukov, S.; Shiran, N.; Belsky, A. (Functional Materials, 2013)
    The problems of radiation damage and afterglow nature for CsI:Eu crystal are discussed. It was determined that the luminescence parameters depend on the X-ray irradiation conditions. Irradiation leads to emission suppression ...
  • Scintillation, phonon and defect channel balance, the sources for fundamental yield increase 
    Gektin, A.; Vasil'ev, A. (Functional Materials, 2016)
    The estimation of the fundamental limits of scintillation efficiency requires the analysis not only of electron channel of the energy transformation but also of the role of interplay between electron and phonon channels. ...
  • Strontium iodide: technology aspects of raw material choice and crystal growth 
    Gektin, A.; Vasyukov, S.; Galenin, E.; Taranyuk, V.; Nazarenko, N.; Romanchuk, V. (Functional Materials, 2016)
    The technological features of SrI₂ crystals production are discussed in this paper. The main reasons of deterioration of the purity and quality of the crystals were identified. It is shown that anionic (OH-group) is the ...
