2019年5月1日 · X-ray photoelectron spectroscopy (XPS) is one of the most powerful experimental techniques for studying the electronic structure of small gas-phase molecules [1, 2], solid materials and their surfaces [1, 3], and large molecules of biological interest [[4], [5], [6]]. This technique has the great advantage that core electron binding energies ...

首选采集 Mg2s 和/或 Mg2p 区域而不是 Mg1s 峰。 XPS 光谱解读. Mg1s 峰通常在 300 eV-390 eV 处伴有俄歇峰。 如果镁颗粒表层被覆盖（例如，被碳层覆盖），即使未观察到 Mg1s 峰，也可以观察到 Mg KLL 俄歇峰。（由于电子动能的差异）

The authors present a review of their research work on the application of X-ray photoelectron spectroscopy (XPS) to characterise thin (~ 3 nm) natural oxide films that spontaneously form on the...

The high-resolution XPS spectra of Mg 2p shown in Fig. 4d showed peaks at 49.84 and 51.15 eV, which were attributed to Mg and MgO, respectively [33], in CQD 3 MgO 40 . In addition, three peaks...

2000年5月1日 · High resolution XPS spectra revealed two distinct oxygen species on the surface films: one assigned to O 2− in MgO, the other to OH − in Mg (OH) 2. Depth profiling revealed that the two species had different depth distributions in the films.

2010年11月1日 · In this figure, Mg2p XPS spectra acquired in the coating layer is also shown to make a comparison. The Mg2p component with higher binding energy is attributed to MgO or MgCO 3, and the one with lower binding energy is attributed to metallic Mg or Mg(OH) 2.

Figure 5A displays the high-resolution spectra of Mg2p, Cl2p, S2p, C1s, O1s, and F1s on the Mg surface with the detailed analysis of the composition of the surface layer by carefully fitting the...

2013年12月27日 · High resolution scans of the Mg2p region at 40–60 eV, the O1s region at 520–540 eV, as well as the C1s region at 280–300 eV were recorded with a step size of 0.05 eV, a pass energy of 10 eV, and 500 ms dwell time.

还是应该查MgO中Mg2p的结合能，我查到的是49.7ev，那么化学位移就是0.7ev了！ 第二个问题就是，分析实验得到的XPS，是要与标准的MgO图谱进行比较，还是与Mg的标准图谱比较（我只能查到Mg的标准图谱）？

It may preferable to acquire Mg2s and/or Mg2p regions instead of the Mg1s peak. Interpretation of XPS spectra. Mg1s peak often accompanied by Auger peaks between 300eV-390eV. If magnesium is buried (under carbon, for example), Mg KLL Auger peaks may be observed even if Mg1s is not (due to difference in electron kinetic energy).
