XPS 光谱解读. S2p 峰具有紧邻的自旋轨道分裂峰 (Δ=1.16 eV，强度比=0.511) 可以观察到硫单质和硫化合物的自旋轨道分裂。 用户通常观察到分裂谱或由于双峰未分离引起的峰形不对称， …

Interpretation of XPS spectra S2p peak has closely spaced spin-orbit components (Δ=1.16eV, intensity ratio=0.511). Effect of spin-orbit splitting can be observed for sulfur elements and compounds.

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）。

The XPS S 2p spectra depicted in Fig. 2A reveal that no S 2p peaks are detected in the CP film, whereas the MSP film exhibits an S 2p spectrum ranging from 166 to 171 eV.

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…

2003年12月10日 · In this work, there was introduced the third SCLS component in S 2p spectra having a distance of 2 eV from the bulk component towards lower binding energy. It is the most surface sensitive one being explained to be due to fracturing of S–S bonds situated near the steps or kinks between the {1 0 0} type planes.

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra. These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user.

The presence of two sulfur species was detected in X-ray photoelectron spectroscopy (XPS) studies of thiol and disulfide molecules adsorbed onto gold surfaces. These species are assigned to bound thiolate (S 2p3/2 binding energy of 162 eV) and unbound thiol/disulfide (S 2p3/2 binding energy from 163.5 to 164 eV).

1999年8月1日 · 高结合能 S 2p 3/2 组分也可以由 Cu(I) 取代到 ZnS 中产生，伴随硫的相关氧化作为电子缺陷位点，而没有 SS 键合、金属缺陷或重组。 XAFS 证据证实了这一分配。

As shown in Figure S5, the XPS spectra of both as-synthesized CuFeSe 2 nanosheets and the CFS-S nanosheets exhibit Cu 2p with two peaks at 932.4 eV and 952.3 eV, and Fe 2p with two peaks at...
