仪器原理: 通过X射线去辐射样品,使原子或分子的内层电子或价电子受激发射出来。被光子激发出来的电子称为光电子。可以测量光电子的能量,以光电子的动能/结合能(Eb=hv-Ek-W)为横坐标,相对强度(脉冲/s)为纵坐标可做出光电子能谱图。从而获得试样有关信息。
技术指标:微区XPS分析(单色化XPS),用于样品微区(>20μm)表面成分分析
主要附件:单色化XPS(Al靶),反射电子能量损失谱(REELS),紫外光电子能谱(UPS)

应用范围:用于各种有机和无机固体材料的表面元素和其价态的定性、定量分析。可用于腐蚀、摩擦、浸润、粘接、催化、包覆、氧化等表面和界面过程的研究。
Instrument model: ESCALAB 250Xi
Manufacturer: Thermo Fisher Scientific Inc. USA
Principle: Inner electrons or valence electrons of the atoms or molecules are motivated and emitted while the sample is irradiated by X-ray. And these motivated electrons are named photoelectrons. Photoelectron spectroscopy can be obtained by analyzing the energy of photoelectron, while the kinetic energy of photoelectron (Eb=hv-Ek-W) is used as abscissa and the relative intensity is used as ordinate. Therefore, the sample information is obtained.
