问了测试中心的老师，说是做一个LMM谱图，但是我经过荷电校正后，这个Cu的LMM谱图上的峰型是对应着CuO的，但是相比较一般的Cu2+的Kinetic Energy(917.8 eV)，我的这个Kinetic Energy竟然在923.8eV，这个合理吗？

2003年10月1日 · Compared with the crystalline compounds Cu 2 O and CuO and metallic Cu, the chemical shifts of the Cu LMM Auger lines are considered to represent the difference of the relaxation effect of the two-hole final state of Cu due to the electron donation ability of the surrounding elements around Cu in the glasses.

感觉反应后主要还是CuO，卫星峰这么明显，分不太出来Cu+，而且从你LMM图中感觉应该在918eV以上，貌似Cu0比较多。 个人意见，仅供参考 guagua (2016-2-17 15:48:10)

1974年1月1日 · Improved techniques have been used to prepare thin films of Cu, CuO, Cu 2 O and Cu 2 S for x-ray photoelectron spectral analysis. The Cu 2p and Cu LMM Auger spectra have been obtained. Photoelectron and Auger chemical shifts as well as qualitative spectral features are found to be useful diagnostics for valence-state characterization of unknowns.

Cu 2p XP and Cu LMM Auger spectra of Cu2O films prepared at (a) −0.5 V, (b) −0.55 V, (c) −0.6 V, and (d) −0.65 V vs. Ag/AgCl. (e) is a reference XP spectrum of CuO powder. The binding and...

In the spectrum of Cu LMM (Figure 2d), characteristic peaks located at 569.8 eV and 568.1 eV are respectively assigned to Cu(I) (Cu2O) and Cu [15], while the peak at 572.7 eV corresponds to Cu(II...

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 determining Cu metal versus Cu (I) in the absence of Cu (II) species.

我的铜基催化剂本来扫出来的LMM谱图在550-600ev之间，按照论坛里的一个帖子提示我将550-600 eV结合能转化成俄歇电子动能，即1486.6-BE，这样就转换到900-930 eV 俄歇谱电子动能了。

2021年12月24日 · The sample modified with a low content of Sn, CuNW-Sn LOW, exhibits Cu 2p (main peak at BE 934.1 eV and shake-up satellite structure) and Cu LMM spectral features of CuO. For both samples, Cu 2p and Cu LMM Auger spectra can be accurately fitted with the peak model described by Biesinger et al. for Cu(OH) 2 and CuO (see details on peak model in ...
