摘　　要：在 L i Nb O3中掺进 Fe2 O3生长了 Fe∶ Li Nb O3晶体。对晶体进行氧化、还原处理 ,测试了 Fe∶ Li Nb O3晶体的吸收光谱以及 Li Nb O3和 Fe∶ L i Nb O3晶体的拉曼光谱 ,研究了氧化还原处理对晶体的光谱影响。Fe∶LiNbO 3crystals were grown by doping Fe 2O 3in LiNbO 3crystals. The crystals were subsequently oxidized and reduced. The absorption spectra and Raman spectra of the Fe∶LiNbO 3crystals were measured before and after the oxidation reduction treatment. The influences of the oxidation reduction treatment on these spectra were investigated.
