“…LiNbO 3 samples with concentrations of 0.1, 0.5 and 1 at.% of Pr 3+ ions were grown from a congruent melt (Li/Nb = 0.94) parallel to the c direction. Details of the growth process are described in [14]. The data presented in this paper were obtained for LiNbO 3 :Pr 3+ with 0.5 at.% of Pr 3+ .…”

The 1 D 2 → 3 H 4 luminescence kinetics of LiNbO 3 :Pr 3+ and LiTaO 3 :Pr 3+ have been measured under high hydrostatic pressure applied in a diamond anvil cell for pressures up to 200 kbar. The luminescence decays have been analysed using the continuous function decay times distribution. Two mechanisms that accelerate the emission decays with increasing pressure have been proposed: the non-radiative depopulation of the 1 D 2 state through the Pr 3+ trapped exciton, dominating in LiNbO 3 :Pr 3+ and pressure-induced increase of the 1 D 2 → 3 H 4 transition probability, dominating in LiTaO 3 :Pr 3+ .

Electron paramagnetic resonance study of congruent LiNbO3 single crystal weakly doped (0.1 wt%) with erbium is reported. The EPR lines originating both from the 167Er isotope with a hyperfine structure, as well as from the evenEr isotopes causing fine structure, are identified. Angular dependence of the EPR lines reveals the presence of several non‐equivalent centers. Deconvolution of the EPR line into several Lorentzian components in a plane perpendicular to the z‐axis (optical c‐axis) allowed us to show the Er3+ center with the lowest (C1) point group symmetry and estimate the values of g‐tensor. The obtained results confirmed the model of non‐ equivalent centers of the rare‐earth ions in lithium niobate having the lowest C1 symmetry due to the presence of intrinsic defects in the near‐neighborhood of RE3+.
