Abstract

A flip-flop effect has been revealed at the anodization of aluminum oxide and subsequent electrochemical deposition of Co/Ni nanoparticles. The angle dependences of the reflection spectra of metallized anodized aluminum oxide films have been measured. Using the conditions of light interference in a thin film, the values of the effective refraction index and film thickness in dependence on the anodization time have been calculated by the recorded interference reflection spectra. The quantitative evaluation of the flip-flop effect has been carried out based on the spectral shifts and the values of spectral changes in the tristimulus values of the CIE L*a*b* system. It has been shown that the effectiveness of the flip-flop effect depended on the acid nature (sulfuric, phosphoric, or chromic) of the anodizing solution. It has been demonstrated that the greatest flip-flop effect is attained at double anodization in chromic and phosphoric acids.

阳极氧化铝膜上的触发器效应

摘要

在氧化铝的阳极氧化和随后的Co / Ni纳米粒子的电化学沉积过程中已经发现了触发器效应。已经测量了金属化的阳极氧化铝膜的反射光谱的角度依赖性。利用薄膜中的光干涉条件，通过记录的干涉反射光谱计算了取决于阳极氧化时间的有效折射率和膜厚度的值。基于谱位移和CIE L * a * b *的三刺激值中的谱变化值，对触发器效应进行了定量评估系统。已经显示，触发器效应的有效性取决于阳极氧化溶液的酸性质（硫酸，磷酸或铬）。已经证明在铬酸和磷酸的双重阳极氧化中获得最大的触发器效应。
