Paper Abstract

Electron paramagnetic resonance (EPR) measurements of LiNbO3: Yb, Pr (0.8wt.%, 0.1 wt.%) single crystals were analyzed for lattice sites of Yb in the crystal and also for the Yb3+ pairs arising. Parameters of the spin Hamiltonian were calculated using EPRNMR program. From the angular variations of the EPR spectra it results Yb3+ ions of C1 symmetry arise in the crystal. Pr3+ ions change parameters of spin hamiltonian for Yb3+ ion. Some results of the absorption measurements were also analyzed for UV-VIS and IR giving evidence, together with EPR results, on Yb3+ location at Li+ sites and Pr3+ location at Nb5+ sites. For comparison absorption spectra of the LiNbO3 doped with 0.5 wt. % Pr3+, 0.8 wt. % Yb3+ were analyzed. Low temperature absorption measurements have shown the presence of low energy phonons responsible for the intensity of the main Yb3+ absorption line in IR as a function of the temperature. Raman spectra confirmed the observation.
