The O 1s XPS spectra show characteristic peaks of C=O or P=O bounds (531.2 eV), as well as C-O-H or C-O-P groups (533.2 eV) and C-O aromatic or P-O-P groups at 534.5 eV...

氧元素 XPS 主峰：O1s 干扰峰：Na KLL、Sb3d、Pd3p、V2p 常见化学状态的结合能：

High resolution XPS spectra of O1s, N1s, C1s and P2p regions for dry [poly-L-arginine/DNA]5 sample: experimental data (solid curve) and fitting results (dashed curve). The 1s peaks were...

O1s的XPS峰一般会分成两个，表面氧和晶格氧，表面氧并不是所说的氧杂质，而是表面的羟基、水啊、氧空位啊什么的，具体的文献都有解释，MgSO4中的氧应该对应于晶格氧，而Mg (OH)2.2H2O应该对应于表面氧，至于三种氧峰 ... 感谢回复！ 您说的MgSO4对应晶格氧、H2O对应表面氧我能理解，但Mg (OH)2也是对应表面氧吗？ 我查了一些数据，金属氢氧化物大多在531eV处，这应该对应的是晶格氧吗？ 感谢回复！ 您说的MgSO4对应晶格氧、H2O对应表面 …

Oxygen X-ray photoelectron spectra, oxygen electron configuration, and other elemental information. Charge referenced to adventitious C1s peak at 284.8eV. The O1s region may be overlapped by peaks from antimony, palladium, or vanadium.

2023年7月3日 · X-ray photoelectron spectroscopy (XPS) is widely used to determine the chemical and electronic states of atoms within a material. However, it is often complex to interpret the O 1s region in metal oxides, where an ∼531 eV binding energy feature appears between lattice oxygen (∼530 eV) and oxygen-containing surface species (∼532 eV).

2021年10月1日 · Metal oxides exposed to water give rise to XPS O1s signal at 532.5–533.0 eV for the irreversibly adsorbed molecular mode as well as, in most cases, to dissociatively adsorbed water molecules at ca. 531.5 eV or close; surface hydroxyls. The following three examples of in situ studies illustrate the process.

Gaussian XPS peak fitting was used to deconvolute the broad spectrum of O 1s at 531.8 eV, which produced two distinct peaks at 531.1 and 532.8 eV which are ascribed to the M − O and M − OH...

1991年3月1日 · 本文的目的是给出 XPS 分析的例子，展示 O 1s 谱带如何受表面碳酸盐的影响。正确的峰分配（例如，O- OH- 物种）需要对碳酸盐贡献的初步确定。尽管检查的样品仅代表 Co 和 La 化合物，但主要结论也可以扩展到其他氧化物系统。
