摘要

研究了在CuO粉末存在下，经高温处理后的LiNbO3单晶OH-基团吸收带深度分布。铜的扩散引起的光吸收变化在垂直于扩散方向的方向上记录下来。揭示了羟基吸收带的强度和位置与铜离子的空间分布的相关性。

OH- Absorption Spectra of Lithium Niobate Crystals Diffusion-Doped by Copper

The OH- groups absorption band depth profiles of LiNbO3 single crystals were investigated after high-temperature treatment in the presence of CuO powder. The changes of the optical absorption caused by diffusion of Cu were registered in the direction perpendicular to the direction of diffusion. The correlation of the OH- groups absorption band intensities and positions with the spatial distributions of copper ions is revealed.
