外来碳污染通常用作 XPS 能谱的荷电基准。 外来 C1s 谱图通常有 C、C-O-C 和 O-C=O 峰。 默认情况下,可将 C-C 峰的结合能设置为 284.8 eV。 但该荷电基准值并非一直有效(例如:铝天 …
XPS chemical shift and valence - EAG Laboratories
The XPS binding energy of an atom is a measure of the electronic environment of the atom. Decreasing the electron density of an atom (such as a C-O bond compared with a C-C bond) …
XPS provides chemical bond information - EAG Laboratories
For a C-O single bond a chemical shift of ~1.5 eV is observed relative to C-C. For a C=O double bond a slightly larger positive charge exists on the carbon atom and a chemical shift of ~2.9 …
