| Abstract: | Perovskite Oxides RECr03 (RE=La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb) were prepared by the means of solid state reaction.The measurments of XRD and XPS showed that the replacement by rare earth element lowers the binding energy(BE) of rare earth ions, compared with their sesquioxides. In the Perovskite Oxides, the BE of Cr2p3/2 increases with the decrease of ionic radius of the RE ion.The reason for the changes of BE are discussed. |
