摘要	The perovskite oxides La0.875-xEuxNa0.125CrO3 were prepared at 1200 degrees C by solid state reaction. XRD, XPS and Eu-151 Mossbauer spectra measurements show that the structures are orthorhombic and their lattice distortion degree increases with x. Cr ions are in mixed valence of +3 and +6. With x increasing, the amount of Cr6+ becomes larger. The covalency and length of Eu-O bonds are the most important factors influencing the isomer shift of Eu-151.
