【摘要】 采用ＦＴＩＲ、ＸＰＳ和ＡＥＳ研究了金属铜表面Ｍ－Ｓ（Ｍ＝Ｍｏ，Ｗ）簇合物膜。结果表明，Ｍｏ（Ｗ）与铜表面的Ｃｕ＿２Ｏ反应，形成了Ｍｏ（Ｗ）－Ｓ－Ｃｕ键；簇合物膜由Ｍｏ（Ｗ）、Ｓ、Ｃｕ、Ｏ元素组成，分别呈＋６、－２、＋１、－２价，膜为多分子层结构并保持ＭｏＳ＿４，或ＷＳ＿２单元，膜表面只有Ｃｕ、Ｏ而不存在Ｍｏ（Ｗ）、Ｓ．膜层厚度与反应时间有关，时间越长，膜越厚。膜为多组分的复杂体系，其颜色是各组分统计分布的结果。更多还原

【Abstract】 The M-S（M=Mo,W）cluster compound films on copper surfaces have been in-vestigated by FTIR , XPS and AES. The results show that Mo（W）-S-Cu bonds wereformed by the reaction of Mo（W）with Cu₂O layer on copper surface. The films are com-posed of Mo（W）,S,Cu and O,each with the valence of +6,-2,+1 and-2,respective-ly. A multimolecular layer structure of the films was verified.Only Cu and O were found onthe film surface, MoS₄ or WS₂ units remain in the inner layers of the films.The thickness ofthe film was found to depend on the reaction time:the longer the time,the thicker the film.The color of the films is probably caused by a statistical distribution of various layers and thefilm is a complicated multicomponent and multilayer system.更多还原
