    • 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 ...

    • Luminescence of oxyfluoride glasses containing YB3+–RE3+ ions 

      Loiko, P. A.; Rachkovskaya, G. E.; Zakharevich, G. B.; Skoptsov, N. A.; Yumashev, K. V. (2016)
      The optical absorption and up-conversion luminescence of oxyfluoride glasses in the system SiO2–PbO–PbF2–CdF2 coactivated by Yb3+–RE3+ ions (where RE = Er, Tm, Ho, Dy, Pr, or Tb) are investigated. Excitation with a laser diode in the IR range (960 nm) gives intense green, blue, and red luminescence. The color characteristics of the up-conversion luminescence in the CIE 1931 system ...
