应该说是结合能(binding energy),和键能没关系的,数据库里应该什么价态都有吧如果测试公司给的图谱,上面有测试的物质是什么,我看得是jeol的 文献中确实是 binding energies ,这个是结合能?compared??with??the??standard??binding energies of elemental nickel and boron, the binding energies of ni0 shifted n...
XPS数据库一般采用NIST XPS database: https://srdata.nist.gov/xps/selEnergyType.aspx 通过这个网站你可以查到几乎xps所需的所有数据包括:对双峰还应考虑两个峰的合理间距、强度比等。 ▲ 网站截图 ▲ XPS表征手册一般采用:Handbook of X-ray photoelectron spectroscopy: a reference book of standard spectra ...
通过测量光电子的能量即可推出电子的结合能(binding energy,BE)。由于原子的电荷密度会对BE产生影响,因此,通过对实测XPS谱图上峰位置相对于标准位置的变化(化学位移)即可推断出该原子的成键结构和元素价态等信息。 测试限制 不同于金属材料,半导体和绝缘体的电子导电性较差,使得这两类物质在测试中发生两方面问题: ...

Cellulose nitrate is evaluated for use as a N(1s) binding energy reference standard in X-ray photoelectron spectroscopy (XPS) analysis of nitrogen-containing organic materials. Cellulose nitrate possess a number of attractive attributes for this purpose of which the most significant is the high N(...
Gold, Latin aurium for "shining dawn", has been one of the most valued precious metals since prehistoric times and is mentioned several times in the Old Testament. Gold has been the standard for monetary exchange in many countries. While the metallic element takes on a yellow color e...
