XPS 谱图解读. K2p 峰具有明显的自旋轨道分裂峰（Δ 氯化物 =2.8eV）。 较弱的 K2p 峰很容易与芳香族化合物中的 C1s (CF 2) 峰或 C1s 卫星结构混淆。 通过识别预期的 K2p 自旋-轨道分量，可以确定 K2p 与 C1s 峰。还检查 K2s 峰，结合能 ~378eV。 一般性注释

2012年1月15日 · In this work we report a core level XPS study of K 2 O–SiO 2 glasses, emphasizing the O 1s, Si 2p and K 2p spectral lines. The XPS data provide evidence for two types of BO atoms and the presence of O 2− ; an oxygen atom not bonded to a silicon atom.

2024年2月1日 · Overall, however, the C 1s - K 2p overlap is generally quite easy to identify and handle because of the spin-orbit splitting and relative positions of the K 2p peaks. The K 2p peaks are close together (they themselves overlap), their spacing is well known, they have a 2:1 area ratio, and they appear at the high binding energy side of the C 1s ...

As shown in the XPS of Mn 2p and W 4f in Figure S5, after K + loading, the Mn 2p core-level binding energy shifts up, indicating an electron transfer from Mn to K. In contrast, the W 4f...

this work aims at providing XPS characterization of numerous commercial K-based reference compounds, including some that were still missing in the literature. In particular, absolute and relative binding energy values are given and compared to correspond-

Primary Peak (XPS Signal) used to measure Chemical State Spectra: K (2p 3/2) at 294 eV Recommended Pass Energy for Measuring Chemical State Spectrum: 50-60 eV (Produces Ag (3d 5/2 ) FWHM ~0.7 eV)

These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user. K 2p3/2 binding energies. K 2p3/2-1/2 splitting is 2.77 to 2.8 eV. Notes: Often will see K 2p peaks in high resolution C 1s spectra.

Two strong peaks appeared at higher binding energy (293.2 and 295.9 eV) in the XPS spectra of two samples, which can be assigned to K 2p 3/2 and K 2p 1/2 (Wu et al., 2016). For O 1s...

XPS and XRD studies indicate the phase pure hexagonal layered P2-type structure of samples. Raman and FTIR spectroscopy reveal the possible bending and stretching vibration modes for Te-O and ...

2021年2月8日 · The XPS full surveys of the artificial and traditional SEI films exhibit five obvious peaks of C 1s, K 2p, K 2s, O 1s, and F 1s (Figure 3a). Furthermore, three new peaks assigned to S 2s, S 2p, and N 1s for the graphite anode with the artificial SEI film are also evident, which arise from the decomposition of the inorganic KFSI.
