On the interpretation of X-ray photoelectron spectra of Pt-Cu ...
2021年1月1日 · First, we thoroughly examine the XPS Cu 3p spectra of pure copper surfaces of different oxidation states, namely Cu°, Cu +, and Cu 2+. Then, the obtained results are applied for the fitting of Pt 4f spectra of both metallic and oxidized Pt-Cu systems.
Copper Spectra – Cu metal - XPS Database
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。 根据 Cu2p 的卫星特征峰能区分铜的氧化态。 二价铜在 943 eV 处可观测到一组卫星特征峰。 氧化铜的 Cu2p3/2 峰有位移,其峰宽大于氧化亚铜峰。 对于氧化亚铜,仅在 945 eV 处观察到一个极弱的卫星峰。 氧化亚铜的 Cu2p3/2 峰未发生位 …
【求助】Cu XPS 中铜的价态区分 - 经验共享 - 分析测试百科网
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
