摘　　要：在以往十多年中,XPS技术用于稀土元素氧化物与卤化物,探讨了稀土元素的内壳谱及其伴峰现象,但对稀土元素配合物的研究报导甚少。本文报导我们新合成的稀土元素-吡啶氧正离子硼氢配合物[Ln(PyO)_7]_2(B_(10)H_(10))_3的XPS及其价带谱结果,而这些研究尚未见文献报导。XPS inner shell. satellite peaks and its valence band spectra of the pyridoxygen complexes of rare earth decahydrodecaborate nave been investigated. The binding energies of the ligand atoms show variation with increasing atomic number of rare earth elements and a specific 'tetrad effect' is observed in the plot of binding energies of ligand atoms versus rare earth atomic numbers. The XPS valence band spectra of different rare earth complexes are characteristic for the rare earth elements.
