EuMO_3的XPS和Mossbauer谱研究

A Study of XPS and Mossbauer Spectra for EuMO_3

对ＥｕＭＯ３进行了ＸＲＤ、ＸＰＳ、ＩＲ和１５１ＥｕＭｏｓｓｂａｕｅｒ谱测量，研究了晶胞参数与离子半径、Ｅｕ４ｄ光电子峰的结合能、同质异能移位的关系。结果表明，Ｅｕ４ｄ结合能和同质异能移位均与Ｂ位离子Ｍ的变化有关，且结合能与同质异能移位成线性关系。

XPS,IR,and 151Mossbauer spectra were measured for EuMO3.The relations of lattice parameters,ionic radii,core level binding energy of Eu4d and isomer shift(IS) were disscussed.It is found that the binding energies of Eu4d and IS are all related to the changes of M ions.The relationship between binding energy and IS is linear.
