Orientation of azobenzene units in self assembled multilayer films of two side chain azo polyelectrolytes was investigated by using polarized UV Vis absorption spectroscopy.
用偏振紫外光谱研究了两种侧链偶氮聚电解质静电逐层自组装膜中偶氮生色团的初始取向。
All materials have strong absorption in EUV region. Therefore, using multilayer coatings is the only approach to construct normal incidence optical systems.
在极紫外波段，任何材料都存在严重的吸收，因此采用多层膜实现高反射率，是构建正入射式光学系统的唯一途径。
