锡表面Mo(W)-S-Sn彩色簇合物膜的组成与结构研究

Investigation on Constitution and Structure of theColored Mo(W) S Sn Cluster Compound Filmon Tin Surface

通过(NH4)2Mo(W)S4溶液浸渍,在金属Sn表面获得了不溶性且具有金属光泽的Mo(W)-S-Sn彩色簇合物膜。FT-IR、F-IR、FT-Raman、XPS和AES研究表明,簇合物膜中存在Mo(W)-S-Sn、端基Mo(W)-S和端基Mo(W)-O键,膜层由Mo(W)、S、Sn和O元素组成,膜为多分子层结构,从AES深度分布曲线的组成恒定区求得了元素的相对原子百分数和膜层厚度。

Colored Mo(W) S Sn cluster compound film as an insoluble metallic luster was coated on tin surface by immersing in (NH)Mo(W)S solution. The results of FT-IR, F-IR, FT-Rmamn, XPS and AES analyses have indicated the existence of Mo(W)-S-Sn, terminal Mo(W)-S and Mo(W)-O bonds in the cluster film which was composed of the elements Mo(W), S, Sn and O. A multimolecular layer structure of the films has been verified. The relative atomic percent contents and thickness of the film was calculated at the constant elemental composition section on the AES profile curves.
