    • Cooperative up-conversion in Eu3+,Yb3+-doped SiO2–PbO–PbF2–CdF2 oxyfluoride glass 

      Loiko, P. A.; Rachkovskaya, G. E.; Zakharevich, G. B.; Kornienko, A. A.; Dunina, E. B.; Yasukevich, A. S.; Yumashev, K. V. (Elsevier, 2014)
      Novel oxy fluoride glass doped with YbF3 and Eu2O3 is synthesized in the SiO2–PbO–PbF2–CdF2 system by melt quenching technique. Its physical properties, as well as the optical absorption of Eu3+ and Yb3+ ions are studied. Spectroscopic properties of Eu3+ ions are modeled within modified Judd–Ofelt theory, yielding absorption oscillator strength, luminescence branching ratios and ...

    • Spectroscopic and photoluminescence characterization of Eu 3+-doped monoclinic KY(WO4)2 crystal 

      Loiko, P. A.; Dashkevich, V. I.; Bagaev, S. N.; Orlovich, V. A.; Yasukevich, A. S.; Yumashev, K. V.; Kuleshov, N. V.; Dunina, E. B.; Kornienko, A. A.; Vatnik, S. M.; Pavlyuk, A. A. (Elsevier, 2014)
      Monoclinic 2 at% Eu-doped KY(WO4)2 is grown by top-seeded solution growth method. Polarizationresolved absorption and stimulated-emission cross-section spectra are determined for this crystal. Spectroscopic properties of Eu:KY(WO4)2 are modeled within conventional Judd–Ofelt theory, as well as theory of f–f transition intensities for systems with anomalously strong configuration ...
