Na 是一种高活性金属，通常在 XPS 谱中仅观察到钠化合物。 钠的存在，尤其在存在氯和强碳氢化合物 C1s 峰时，可能表明未戴手套进行手动操作造成了污染。 由于扩散过程，玻璃材料表面可能会表现出钠含量增加。 将玻璃暴露于更高能量的电子（几百 eV 或更高）可能会导致 Na 扩散到主体中或穿过照射区域的表面。 这种柔软的蜡状银色活泼金属于1807年由 Humphry Davy 爵士分离出来，它在很久以前就已在化合物中被识别出来。 在中世纪的欧洲，钠的化合物被用作治疗 …

Na is a highly reactive metal and usually only sodium compounds will be observed in XPS spectra. The presence of sodium, especially with the presence of chlorine and an intense hydrocarbon C1s peak, can indicate contamination from manual handling, without the …

In the F1s and Na 1s region ( Figure 3 (c, d)), the spectra are dominated by peaks that can mainly be assigned to NaF resulting from NaPF 6 decomposition. Additionally, some other sodium salts...

For surface analysis, we used both Na 1s and Na 2s spectra in order to probe different sampling depths: Na 1s provides information about the few top surface layers only, while the Na 2s signal...

2020年9月18日 · X射线光电子能谱仪 (X-ray photoelectron spectroscopy) 简称 XPS 是表面分析的有力工具，它提供了元素价态等的信息，其中结合能是判断元素的关键，铄思百检测在这里与大家分享XPS结合能对照表，希望对大家的科研有帮助。

2006年7月1日 · Na1s XPS spectra of different carbon blocks after electrolysis for 45 min (semi-graphitic blocks) and 60 min (graphitic and graphitized blocks), respectively. The spectra were normalised to maximum intensity.

X-ray photoelectron spectra (XPS) indicated the seepage of dopants in ZnO nanowires by substitution of Zn. Shallow acceptor levels (LiZn, NaZn, KZn) worked as electron...

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.

2019年1月1日 · Aiming at a more comprehensive understanding of the solid electrolyte interphase (SEI) in sodium ion batteries (NIBs), a detailed X-ray photoelectron spectroscopy (XPS) investigation of the few-nanometer thick passivation film formed on hard carbon (HC) in contact with various Na + -ion conducting electrolytes is reported.

Na is a highly reactive metal and usually only sodium compounds will be observed in XPS spectra. The presence of sodium, especially with the presence of chlorine and an intense hydrocarbon C1s peak, can indicate contamination from manual handling, without the …
