“…Some differences in hyperfine constants for Cu 2+ centres in LTB and KLTB glass network can be related to slightly different local environments in their second coordination sphere. The Cu 2+ similar as Mn 2+ impurity centres are incorporated into the Li (or K) sites of the LTB and KLTB glass network with coordination number to oxygen N = 4 ÷ 6, because local environments in glasses are closely similar to corresponding crystals [23,24].…”

The electron paramagnetic resonance spectra of the glasses with Li 2 B 4 O 7 and KLiB 4 O 7 compositions doped with Mn and Cu were investigated. On the basis of obtained EPR spectra analysis it was shown that the Mn and Cu impurities are incorporated into the glass network as Mn2+ EPR spectra in the glasses with Li2B4O7 and KLiB4O7 compositions are characterised by the following parameters, measured at T = 300 K: isotropic g-factor (giso = 2.00 ± 0.05), isotropic hyperfine constant (Aiso = (8.65 ± 0.05) mT) and peak-to-peak linewidth of hyperfine components ∆Bpp = (3.50 ± 0.05) mT. The Cu 2+ EPR spectra in the glasses with Li2B4O7 and KLiB4O7 compositions, registered at T = 300 K are characterised by the same g-values (g = 2.34 ± 0.05, g ⊥ = 2.06 ± 0.05) and peak-to-peak line width of hyperfine components (∆B pp = (5.11 ± 0.05) mT, ∆B ⊥ pp = (1.80 ± 0.05) mT), whereas anisotropic hyperfine constants show some differences (A = (14.28 ± 0.05) mT, A ⊥ = (2.34 ± 0.05) mT for glass with Li 2 B 4 O 7 composition and A = (14.21 ± 0.05) mT, A ⊥ = (2.55 ± 0.05) mT for glass with KLiB 4 O 7 composition). The possible local structure of the Mn 2+ and Cu 2+ centres in the lithium and potassium-lithium tetraborate glass network has been considered.
