摘要
通过ＬｉＮｂＯ３：ＭｇＯ（６７ｍｏｌ／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。
Abstract We have investigated the structure of the crystal LiNbO
3:MgO at both low temperature and room temperature.The results showed that the crystal structure
had changed little after doping of Mg 2+ .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.
