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.
