| 摘 要： | 通过LiNbO3：MgO(6.7 mol/kg)晶体在常温和低温下的喇曼光谱分析，研究了掺Mg2+后晶体结构的变化情况．研究结果表明，常温下晶格略有畸变，个别的散射峰有耦合现象存在，随温度降低，耦合逐渐减少，但掺Mg2+后晶格基本结构并无变化.关键词：

| Abstract: | We have investigated the structure of the crystal LiNbO3: MgO at both low temperature and room temperature. The results showed that the crystal structure had changed little after doping of Mg2+. At room temperature the lattice showed distorted a little, which caused the appearance of overlaping of some individual scattering peaks. As the temperature decreased, the overlaping reduced gradually. |
