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.
