摘要： 用高温高压法合成了Sr1-xEuxTiO3(x=0.0,0.1,0.2,0.3,0.4,0.5)及Ba0.3Eu0.7TiO3化合物。结果表明,所有样品均为立方结构,样品中存在Eu(Ⅱ)和Eu(Ⅲ)的混合价。Eu3+的掺入直接影响了Sr离子与氧离子的结合,使Sr3p3/2的结合能随x的增加而增加。

Abstract: The high pressure and high temperature method was first used to synthesize the compounds of Sr1-xEuxTiO3(x=0.0, 0.1, 0.2, 0.3, 0.4, 0.5) and Ba0.3Eu0.7TiO3.The analysis of X-ray diffraction shows that all of the samples are in single phase and belong to cubic system.The measurement of XPSindicates tht there is a mixing valence of Eu(Ⅱ) and Eu(Ⅲ);and the interaction between Sr ion and oxygen anion was influenced by doping Eu3+and the binding energy of Sr is increased with x increasing.

Key words: Valence fluctuation, XPS, Synthesizing at high pressure and high temperature
