【摘要】本文详细介绍了利用气相交换平衡 ( vapor transportequilibration:VTE)技术获得近化学计量比铌酸锂晶体薄片及其处理工艺 .通过测量其 OH-红外吸收谱线宽及吸收边的位置 ,分析确定晶体薄片中的 Li2 O含量为4 9.9% ,即 [Li]/ [Nb]=0 .996 ,接近其化学计量比更多还原

【Abstract】 This paper reports the technique of vapor transport equilibration (VTE) to obtain near-stoichiometric LiNbO 3 plate. OH - absorption spectra and the position of absorption edge were measured, and the lithium oxide content about 49.9% in the crystal was estimated from these results, which is close to the ideal stoichiometry of LiNbO 3.更多还原
