Oxygen X-ray photoelectron spectra, oxygen electron configuration, and other elemental information. Charge referenced to adventitious C1s peak at 284.8eV. The O1s region may be overlapped by peaks from antimony, palladium, or vanadium.

具体而言, 各黑色素产物的 C 1s 区域由三种信号峰 组成, 分别对应 C＝C (284.8 eV)、C＝O (286.3 eV)和 C (O)-O (288.9 eV)键结构, 均源自真黑素结构 [25] [26] [27] (图 S1, 见支持信息). 对应于 O 1s 区域的 O＝C (533.4 eV)、 O-C (531.7 eV) [27]...

Figure 2 shows the O 1s XPS spectra of the IGZO films with various thicknesses. The O 1s spectra can be resolved into three nearly Gaussian distribution peaks approximately centered at...

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 XPS spectra. These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user. Table 1.

Common oxygen, O (1s) binding energies: Many (pure) oxide samples exhibit a secondary structure to higher binding energy of the main lattice oxygen peak. Careful consideration of the sample history can aid in the identification of this peak. Commonly, this may be ascribed to surface hydroxyl (OH) groups or even defects in the metal oxide lattice.

The O (1s) BE of the hydroxide (water) contamination normally appears 0.5 to 1.0 eV above the oxide peak Sodium (Na), Potassium (K), Oxygen (N) and Oxygen (Cl) are common trace to low level contaminants

As demonstrated by the C 1s, O 1s, Na 1s and F 1s spectra after different sputtering times (Figure 3 (a-d)), the m-Sn electrode's surface in 1 M NaPF 6 -DME electrolyte is clearly covered...

2024年8月1日 · Here we present accurate, quantitative Mn 2p and O 1s NEXAFS spectra of MnO, MnSO4, Mn 3 O 4, Mn 2 O 3, α-MnO 2, β-MnO 2, and KMnO 4, measured using both transmission and total electron yield X-ray absorption techniques. An example of the use of these reference spectra in a study of Zn/MnO 2 batteries is given.

2023年7月3日 · X-ray photoelectron spectroscopy (XPS) is widely used to determine the chemical and electronic states of atoms within a material. However, it is often complex to interpret the O 1s region in metal oxides, where an ∼531 eV binding energy feature appears between lattice oxygen (∼530 eV) and oxygen-containing surface species (∼532 eV).
