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.

主要采集 Cu2p 峰及 Cu LMM 峰。 与 Cu2p 峰相比，Cu LMM 峰观察到的化学位移更大。 仅采集 Cu2p 可能难以区分化学态。 长期暴露于 X 射线或离子轰击会使二价铜还原，Ar 离子团簇模式溅射或者尽量减少 X 射线暴露可避免这种效应。 XPS 光谱解读

2023年6月15日 · Peak-fitting parameters for improved fitting of Cu 2+ in quantitative XPS. The photoemission spectra of Cu 2 p are one of the most studied. Its analysis is especially challenging because, among others, the peaks for Cu 0 and Cu 1+ overlap, and Cu 1+ and Cu 2+ coexist under many conditions.

Cu2O/CuO/CuS electrocatalyst was prepared by thermal oxidation of cleaned copper mesh in the air into Cu2O/CuO and CuS was deposited on oxide surface using facile successive ionic layer...

2017年5月12日 · Chemical state X-ray photoelectron spectroscopic analysis of copper species is challenging because of the complexity of the 2p spectra resulting from shake-up structures for Cu (II) species and overlapping binding energies for Cu metal and Cu (I) species.

Extended X-ray absorption fine structure analysis revealed that the existence of Cu-Cu bonding endowed the layer-structured q-CS with semiconductor properties, such as appreciable interband ...

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.

1. 如何非常详细地描述 XPS 实验结果？ 举例： X-ray photoelectronspectroscopy (XPS) was used to characterize the Cu oxidation state. The coexistence of Cu(I) and Cu(II) in fresh 3K-Cu-20TiO 2 catalyst is evidenced...

In this work, Sn and Ag doped PbS/PVA nanocomposites, in three different concentrations were successfully prepared using the low-cost and simple method of chemical bath deposition (CBD). X-ray...
