角分辨 XPS 是鉴定这些氮化学状态的深度分布情况的适当方法。 金属氮化物（例如 TiN）的 N1s 峰形可能复杂且特殊，可能存在表面氮氧化物。 对于 TiN 样品原样，其 N1s 区域的氧化氮化物状态对应的结合能比纯氮化物状态低。 氧化通常导致谱峰向高结合能方向位移（例如 NiSi 2 O 对比 NSi 3）。 N1s 和 Ta4p 3/2 区域之间的重叠可以通过峰拟合进行分离。 例如，在分析 TaN 时，这种方法很必要。 含氮的芳香族聚合物（例如，聚酰亚胺）可能产生较弱的 π-π* 卫星特征峰， …

Angle-resolved XPS is the appropriate method for identifying the depth distributions of the nitrogen chemical states. N1s peak shapes for metal nitrides (e.g. TiN) can be complex and unusual, possibly with presence of surface oxynitrides.

n1s XPS（X光光电子能谱）的分峰是指N1s电子能级的X射线光电子峰的分布情况。 N1s电子能级通常是指氮原子中的1s轨道。 在XPS谱图中，N1s电子能级的峰位通常在392-404 eV范围内。 在n1s XPS谱图中，通常可以观察到多个ቤተ መጻሕፍቲ ባይዱ峰。 这些分峰的位置和强度可以提供关于材料中氮元素化学环境和化学键的信息。 常见的N1s分峰包括： n1s xps的分峰-1. N-H键：位于396-399 eV范围内，表示与氢原子形成N-H键的氮原子。 2. N-C键：位于400-403 eV范围内， …

The properties of nitrogen centres acting either as hydrogen-bond or Brønsted acceptors in solid molecular acid-base complexes have been probed by N 1s X-ray photoelectron spectroscopy (XPS) as...

2020年6月1日 · To improve the interpretation of XPS spectra of nitrogen-doped carbons, the C 1s, N 1s and O 1s core level energy shifts have been calculated for various nitrogenated carbon structures via DFT.

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.

2016年11月1日 · The as-deposited films typically exhibit two strong N1s peaks corresponding to pyridine-like, and graphite-like, at ∼398.2 eV and ∼400.7 eV, respectively. Comparison between in situ and air-exposed samples suggests that the peak component at ∼402–403 eV is due only to quaternary nitrogen and not oxidized nitrogen.

2019年4月4日 · The calculated XPS binding energies of the N 1s state for graphitic, pyrrolic, pyridinic, and chemisorbed nitrogen in N-doped graphene are 401.5, 399.7, 397.9, and 396.6 eV, respectively, and hydrogenation of pyridinic N shifts its peak to 400.5 eV.

2020年9月28日 · As such, for the simulation of the N1s XPS spectra, a scaling factor of 1.038, obtained from dividing the experimental value of acridine (398.8 eV) by the calculated value of acridine (384.03 eV), was multiplied to all of calculated binding energies to compensate for the difference be-tween the calculated values and experimental values [57,58 ...
