The peaks of Ti 2p 1/2 and Bi 4d 3/2 are partially overlapped (Fig. 5a), leading to a broad bump in the vicinity of 464.5 eV. The XPS peaks at 441.4 and 465.4 eV are assigned to Bi 4d 5/2...

Interpretation of XPS spectra Bi4f region has well-separated spin-orbit components (Δ=5.3eV). Peaks in the Bi4f region have an asymmetric peak shape for bismuth metal.

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 paper presents the results of theoretical calculations of the Bi and Sb energies shifts observed in X-ray photoelectron spectra due to chemical bonds formation in Sb2S3 and Bi2S3 crystals.

The binding energies of the constituent elements are obtained from its high-resolution XPS scan spectra (Fig. 4). The Bi 4f peak is composed of two Bi 4f 5/2 and Bi 4d 7/2 peaks at...

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.

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.

请问楼主解决了吗，我也遇到了相同的情况，我查了相关文献中间两个峰属于 S2p轨道 符合强度比0.5以及Δ=1.16eV左右， 两个属于Bi的峰也符合面积比4：3。那该怎么分析呀，是直接两个元素放在一张图里进行绘图嘛

2006年8月1日 · The strongest peaks of Bi 4f, Bi 5d, I 3d, and I 4d were chosen for investigating peculiarities of the core-level XPS in this quasi-one-dimensional semiconductor. XPS of the broken crosswise and lengthwise samples are very similar.

The 1:1:4 stoichiometric ratio of Bi:O:V in BiVO 4 was the whole element ratio of BiVO 4 structure, including the internal and external parts. However, XPS is a surface-sensitive quantitative spectroscopic technique that could not detect the internal element composition of BiVO 4.
