摘要: 磺化酞菁铜多层膜体系是利用Langmuir-Blodgett技术制备的有序有机分子膜,它对于XPS测试有很好的稳定性,本文在固定电子出射角的条件下利用XPS方法研究了不同厚度的膜样品中Cu2P3/2、Ni1v、S2p峰强度的变化规律,讨论了膜内分子有序排列引起的散射效应对电子平均自由程的影响。

Abstract: Multilayer system of copper phthalocyanine-tetrasulphonate is an ordered organic molecular film assembled by LBtechnique. It is very stable for XPSmeasurement. In this work, we studied the peak intensity variation of Cu2P3/2、Ni1v、S2p in the samples with different thicknesses of the film at a-constant take-off-angle and obtained the inelastic mean free path 26, 22, 48Å respectively. We also gave explanation to the influence of scattering effect caused by the ordered molecular orientation on the inelastic mean free path.
