本文中，作者制备了一种CuMn 普鲁士蓝类似物，为了表征材料中Mn的价态，作者分析了Mn2p的XPS谱峰。 初看起来，这个分峰结果是没什么问题的，背底正确，拟合结果也算良好。 但恰恰是这样的分峰最可能误导新手，因为这里Mn3+的位置是不对的。 从图4可知，Mn2+和Mn3+的位置和峰形都是比较接近的，仅仅利用Mn2p是无法区分的。 鉴于不同价态Mn元素的Mn3s峰具有不同的分裂能（图5），专业的论文常常利用Mn3s来分析。 图4不同价态锰元素的结合能及其峰形. …

Ni2p 3/2 peak structures and binding energies reflect two energetic contributions. The major contribution is that associated with the electrostatic field produced by ejection of the Ni (2p) photoelectron, the minor contribution is the relaxation energy associated with filling unoccupied, conduction band 3d 9 and 4s Ni metal orbitals.

2006年5月1日 · Fig. 2 shows the Ni 2p 3/2 XPS spectrum from clean nickel metal with the two obvious satellite intensities fit by broad peaks (FWHM 2.5 eV) with BE near 3.7 eV (minor) and 6.0 eV (major) above the main line at 852.6 eV.

2023年1月1日 · By fitting both branches of the metallic Ni 2p spectrum, it was possible to resolve two previously unreported satellite peaks in the Ni 2 p1/2 portion of the spectrum. For the partial oxidation of the nickel surface, we analyzed the Ni 2p, O 1 …

在 XPS测试 谱图中，对于带2p、3d、4f标识的元素，比如S2p、Ba3d、Pb4f等元素；由于 自旋劈裂效应 ，当这些元素存在一种 化学态 时，就会劈裂成两个不同属性的峰，对应XPS谱图通常会存在两个峰（过渡族元素除外，因其存在各类型伴峰，谱图比较复杂）。

xps，即x射线光电子能谱。原理简单来说是将x射线光子入射到样品上，将样品的光电子和俄歇电子激发出来。 在阅读文献中，经常可以看到xps图谱，用来分析样品表面元素的价态变化、成分和分子结构 下面以一个图来举例…

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

Ni2p XPS scan spectra were depicted in figure 4(b), two peaks appeared at 853.6 eV and 855.3 eV which resemble the Ni 2+ 2p 3/2 and Ni 3+ 2p 3/2 bonding states respectively, the peak at 861...

使用 X 射线光电子能谱 (XPS) 对暴露于氧气的清洁金属和部分氧化镍的表面组成进行了定量研究。通过拟合金属 Ni 2 p光谱的两个分支，可以解决光谱的 Ni 2 p 1/2部分中两个以前未报告的卫星峰。对于镍表面的部分氧化，我们分析了 Ni 2 p、O 1 s和 C 1 s角分辨 XPS 光谱。
