  • Deep traps in KMgF₃ and LiBaF₃ crystals 
    Gektin, A.V.; Shiran, N.V.; Neicheva, S.V.; Krasovitskaya, I.M. (Functional Materials, 2004)
    The influence of the high temperature annealing in air to the deep traps formation in KMgF₃ and LiBaF₃ fluoroperovskites was the subject of this study. An additional absorption and blue emission connected with O²⁻ ions ...
  • Radiation induced defects in M₁₋ₓPrₓF₂₊ₓ (M²⁺ = Ca, Sr, Ba, x = 0.35) solid solutions 
    Boiaryntseva, I.A.; Shiran, N.V.; Gektin, A.V. (Functional Materials, 2012)
    Radiation-induced processes in M₁₋ₓPrₓF₂₊ₓ (M²⁺ = Ca, Sr, Ba, x = 0.35) solid solutions have been studied. It is shown that the radiation coloration of M₀.₆₅Pr₀.₃₅F₂₃₅ crystals is due to the trapping of charge carriers at ...
  • ¹S₀-luminescence in Ca₁₋ₓPrxF₂₊ₓ crystals 
    Boiaryntseva, I.A.; Shiran, N.V.; Gektin, A.V.; Stryganyuk, G.B.; Belsky, A.N.; Shimamura, K. (Functional Materials, 2012)
    Luminescence properties of CaF₂:Pr (0.2 mol %) and Ca₀.₆₅Pr₀.₃₅F₂.₃₅ crystals were studied at 10 K. Excitation and emission spectra show two types of the Pr³⁺ centers with the typical ¹S₀ —> 4f² radiative transitions. High ...
