摘要: 合成了通式为LnL3Cl3·2H2O(Ln=Eu,Tb,Ho,Tm;L=L-谷氨酰胺)的固体配合物。用XPS辅以元素分析、热分析及IR光谱研究了配合物的组成及性质。观察到配合物中O1a、Ln3d、Ln4d和Cl2p结合能的变化,并发现Eu配合物Eu3d谱峰的伴峰结构,讨论了伴峰产生的机理。

Abstract: The title complexes with a composition LnL3Cl3· 2H2O(Ln=Eu,Tb,Ho and Tm; L=L-glutamine) were synthesized and characterized by XPS combined with elemental analysis, thermal analysis and IRspectra. The change of binding energies of O1a, Ln3d, Ln4dand Cl2p, took place obviously because of the coordination, and the satellite peaks appear in XPS3d spectrum of Eu complex. The mechanism of formation of satellite peak is discussed.
