| 摘要: 研究MoS42-在钢表面发生配位化学反应所形成的具有装饰效果的多种彩色簇合物膜。FT-IR、F-IR、FT-Raman、 XPS和AES分析表明簇合物膜由Fe、Mo、 S、 O元素组成，在膜表面铁以Fe(Ⅲ)、钼以Mo(Ⅵ)状态存在，而在膜内层以Fe(Ⅱ)、Mo(Ⅳ)和Mo(Ⅵ)共存，S和O都呈-2价。从AES深度分布曲线的组成恒定区求得了各元素的相对原子百分浓度和膜层厚度，反应时间越长，膜越厚，膜为多分子层结构。 |

| Abstract: Cluster compound films with various colours for decorative purpose had been formed by the coordination reactions of MoS42- on the surface of steel. The results of FT-IR, F-IR, FT-Raman, XPS and AES analyses showed that the cluster films were composed of the elements Fe, Mo, S and O. Fe existed as Fe(Ⅲ) and Mo existed as Mo(Ⅵ) in the surface of the films, but as Fe(Ⅱ), Mo(Ⅳ) and Mo(Ⅵ) in the internal layer of the films, S and O were -2 valence states. The relative atomic percent contents and the thickness of the films were calculated at the constant elemental composition section on the AES profile curves. The longer the reaction time, the thicker the films, thus a multimolecular layer structure of the films was verified. |
