用红外透射率分析方法研究了氧化镍薄膜在原始、致色和消色状态的红外透射率光谱，用Ｘ－射线衍射方法测量了在ＫＯＨ和ＬｉＣｌＯ４－ＰＣ电解液中致色和消色时，氧化镍多晶薄膜在（１１１）和（２００）方向衍射峰位的移动，分析了注入离子种类和离子注入位置，认为在ＫＯＨ电解液中致色时，注入离子为ＯＨ－，离子的注入位置在晶粒的间界。在ＬｉＣｌＯ４－ＰＣ电解液中，Ｌｉ＋离子的注入位置同样在晶粒的间界 The infrared transmittance spectra of the nickel oxide films in the original, induced and achromatic states were studied by infrared transmittance analysis. When the color and achromaticity of KOH and LiClO4-PC were measured by X-ray diffraction, In the (111) and (200) directions, the diffraction peaks of NiO polycrystalline thin films were shifted, and the species of ions and ion implantation sites were analyzed. It is considered that when ions are colored in KOH electrolyte, the implanted ions are OH-. In the grain boundaries. In LiClO4-PC electrolyte, Li + ions are implanted at the same boundaries of the grains
