Peak is much broader than O1s XPS components. If a particularly large chemical shift is observed, it could be due to O-F x bonding. A big loss feature is often observed to higher binding energy of the main O1s peak. Oxygen will always be present on samples exposed to the atmosphere, either due to adventitious contamination, oxidation, or water.

当峰大致确定好后，可选择“XPS Peak Processing”中的峰号，选中 相应的峰，并通过调节右框中的参数调节峰的形状位置等，通过“Accept”确定或通过“Delete Peak”删除选中的峰。待所有峰确定好后，选择“Optimise All”，可多次点击以优化，得到初步分峰结果如下图。

When using theoretically calculated Scofield cross-section values, the data must be corrected for the transmission function effect, use the calculated TPP-2M IMFP values, the pass energy effect on the transmission function, and the peak area used for calculation must include the electron loss peak area, shake-up peak area, multiplet-splitting ...

2023年7月3日 · This work will rectify many misinterpretations of XPS data of the O 1s region in metal oxides, provide guidance for precisely understanding the oxygen states of a material, and subsequently enable the real origin of material properties to be revealed.

选择Add Peak，选择合适的Peak Type(如s,p,d,f),在Position处选择希望的峰位，需固定时点fix前的小方框,同时还可选半峰宽（FWHM）、峰面积等。 各项中的constaints可用来固定此峰与另一峰的关系。

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...

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.

Common oxygen, O (1s) binding energies: Many (pure) oxide samples exhibit a secondary structure to higher binding energy of the main lattice oxygen peak. Careful consideration of the sample history can aid in the identification of this peak. Commonly, this may be ascribed to surface hydroxyl (OH) groups or even defects in the metal oxide lattice.
