1995年10月1日 · X 射线光电子能谱 (XPS) 表明，每个样品的 C 1s 包络主要是三个峰的卷积，这些峰可归属于 sp2 杂化碳、sp3 杂化碳（从 sp2 峰偏移约 1 eV）和 sp2 卫星峰值，可能是由于 π-π ∗ 跃迁。

2016年12月1日 · To improve the self-consistency of the XPS interpretation a method is proposed based on a 7 peak C1s deconvolution, 3 C C peaks, 3 oxygenated peaks, and pi-pi* transition peak. Deconvolution of the O1s by 4 peaks is used to determine O C and O C contributions which provide upper and lower bounds for the related C1s peaks: C O, C O and COO.

1 天前 · The surface chemical composition of the LIPG surface was performed using an Argus Omicron NanoTechnology X-ray photoelectron spectrometer (XPS). XPS spectroscopy was performed on the sample after electrical measurements. The analysis was performed at room temperature with a base pressure below 1.1 × 10 −9 mbar.

在 XPS 谱中最常见的伴峰包括 携上峰，X射线激发 俄歇峰 （XAES）以及XPS价带峰。 这些伴峰一般不太常用，但在不少体系中可以用来鉴定化学价态，研究成键形式和电子结构，是XPS常规分析的一种重要补充。 1. XPS的携上峰分析. 在光电离后，由于内层电子的发射引起价电子从已占有轨道向较高的未占轨道的跃迁，这个跃迁过程就被称为携上过程。 在XPS主峰的高结合能端出现的能量损失峰即为携上峰。 携上峰是一种比较普遍的现象，特别是对于共轭体系会产生较多的 …
