Two sets of 2p peaks were seen in the Cu XPS 2p core-level spectra; the first set included Cu 2p 3/2 and Cu 2p 1/2 peaks at 932.2 and 952 eV, respectively, which indicate the presence of...

XPS确实很难区分Cu (0)和Cu (I)，用俄歇谱来区分是可以做到的。 如果lz需要，给个邮箱，我把Cu的XPS图谱发给你，可以按照图谱数据区分铜的零，一，二价

Interpretation of XPS spectra Cu2p peak has significantly split spin-orbit components (Δ=19.75eV, intensity ratio=0.508). It is possible to distinguish Cu oxidation states using satellite features of …

Accurate Cu (0):Cu (II) ratios for samples containing a mixture of Cu (0) and Cu (II) rely on determining an accurate ratio of the main peak /shake-up peak areas (A1s/Bs) for a 100% …

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 …

The different oxidation states of copper such as Cu (II), Cu (I) in complexes or oxides and Cu (0) can be analyzed from the binding energies around 932 and 952 eV with slight differences by...

Although the equipment possesses good energy resolution (0.48 eV), it is still difficult to distinguish Cu+ from Cu as their difference of the 2p3 energy (0.20 eV) is less than the energy …

2022年6月16日 · When using the electron flood gun, the instrument operator should adjust the voltage and the XY position of the electron flood gun to produce peaks from a strong XPS …

The Cu LMM peak shape (in addition to the Auger parameter and Cu 2p3/2 peak position and shape) can also be useful in determining Cu chemical states. It is particularly useful when …
