提出了一种新方法，在外部施加电场的情况下，利用 700°C 退火，使掺有大量氧化铁（0.05–3 wt. % Fe2O3）的铌酸锂晶体 (LiNbO3) 几乎完全氧化。处理导致Fe2+和Fe3+离子的浓度比小于2×10-3。 LiNbO3 中铁的强氧化作用降低了光折变效应，因此对于非线性光学应用特别感兴趣。
A new method is presented, allowing the nearly complete oxidization of lithium niobate crystals (LiNbO3), doped with large amounts of iron oxide (0.05–3 wt. % Fe2O3) utilizing annealing at 700 °C in the presence of externally applied electric fields. The treatment results in a concentration ratio of Fe2+ and Fe3+ ions of less than 2×10-3. Strong oxidization of iron in LiNbO3 reduces the photorefractive effect and is therefore of particular interest for nonlinear-optical applications.
