本文利用TSSG方法生长了不同掺Fe2O3浓度的Zn∶Fe∶LiNbO3晶体,并对晶体进行了红外光谱、紫外光谱、晶格常数和居里温度的测试和分析.利用二波耦合实验测得的写入和擦除曲线,计算了晶体的写入时间常数、擦除时间常数和最大衍射效率.并讨论了Fe2O3的掺杂对材料结构和光折变性能的影响机制.

LiNbO3 crystals doped with the same concentration of ZnO and with the different concentration of Fe2O3 have been grown by a top-seeded-solution-growth (TSSG) method. The IR transmittance spectra, UV-Vis absorption spectra, lattice constants, and Curie temperature were measured. In two-wave coupling experiments, writing and erasure curves were measured, and writing time constants,erasure time constants, and maximum diffraction efficiency of the crystals were obtained from the curves. The influences of Fe2O3 doping concentration on photorefractive properties were studied.
