Abstract

Hf:Fe:LiNbO₃ crystals were grown by the Czochralski technique with various ratios of Li/Nb = 0.946, 1.05, 1.20 and 1.38 in the melt. The crystal composition and defect structure were analyzed by XRD, UV-Vis and IR spectroscopy. The results show that the threshold concentration of Hf in LiNbO₃ crystals decrease with the increasing of the Li/Nb ratio; when the Li/Nb ratio is 1.05, the threshold concentration of Hf is less than 2 mol%, largely under the threshold concentration of Hf ions in congruent Hf:Fe:LiNbO₃ crystal (4 mol).¹³ With the increase of Li/Nb, Hf ions first replace the Nb_Li⁴⁺; when the concentration of Hf ions is higher than the threshold value, Hf ions occurs on normal Nb and Li sites.
