摘要 | The valence fluctuations of terbium and europium were studied using in situ electrical resistance measurement under high pressure and high temperature, X-ray diffraction, X-ray photoelectron spectra and Eu emission spectra. The synthesis process of CeTbO3 under high pressure can be marked by the valence fluctuation of Tb4+ --> Tb3+. The relationship between the intensity ratio, I, of the higher binding energy peak to the lower one and the content ratio, Z, of Tb4+/Tb in Tb4d photoelectron spectra can be described by the equation I = -0.98Z2 + 2.15Z (0 less-than-or-equal-to Z less-than-or-equal-to 1). Using this equation the valence state of terbium and its effect on the superconductivity in Eu1-xTbxBa2Cu3O7-delta were investigated. In addition, the phenomenon of pressure-induced valence fluctuation was also observed in the SrB2O4:Eu system. |
