| 摘 要： | 利用固相反应合成了稀土取代的复合氧化物Ｅｕ_（０．５）ＲＥ_（０．５）Ｆｅ_（０．５）Ｍｎ_（０．５）Ｏ_３（ＲＥ＝Ｌａ，Ｐｒ，Ｎｄ，Ｓｍ，Ｇｄ，Ｔｂ，Ｄｙ，Ｈｏ，Ｅｒ，Ｔｍ，Ｙｂ）．测量了这些化合物的ＸＲＤ和ＸＰＳ谱。在ＸＰＳ研究中发现，稀土取代而使稀土元素本身的结合能相对于其倍半氧化物中的有所降低；在取代的复合氧化物中，随着ＲＥ离子半径的减小，Ｆｅ、Ｍｎ的结合能随之增加。

| Abstract: | Complex oxides replaced by rare earth ions, Eu0.5RE0.5Fe0.5Mn0.5O3(RE=La, Pr,Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb) were prepared by the solid state reaction method.Measurements by XRD and XPS were carried out. The study of XPS indicates that the replacement by rare earth causes the decrease of the binding energy(B. E. )of rare earth ions,compared to their sequioxides. And in the replaced oxides, the binding energy of Fe2p3/2 and Mn2p3/2 increases with the decrease of ion radius of RE ion. The reasons for the changes of B.E. are discussed. |
