采用共沉淀法合成了8 YSZ：Eu 3+粉体。研究了8 YSZ：Eu 3+粉体在水热降解不同时间后的物相组成和荧光性能的变化。利用透射电子显微镜（TEM）和扫描电子显微镜（SEM）观察了烧结粉末的形态和显微结构。利用XRD、拉曼光谱、光致发光光谱和衰减曲线等测试手段研究了粉体的物相组成变化和荧光性能变化。结果表明：8 YSZ：Eu 3+粉体为纯四方相结构。在水热降解条件下，由于OH-与氧空位的反应，四斜晶系转变为单斜晶系，从而改变了粉体的荧光性质。
In the present study, 8YSZ:Eu3+powder was synthesized using co-precipitation route. The evolution of phase composition and fluorescence properties of 8YSZ:Eu3+powder have been assessed after being subjected to hydrothermal degradation for different times. Morphology and microstructure of the sintered powder were observed by transmission electron microscope (TEM) and scanning electron microscope (SEM). XRD, Raman spectra, photoluminescence (PL) spectra and the decay curve were used to evaluate the phase composition variation and fluorescence properties variation of the powder. The results showed that 8YSZ:Eu3+powder had a pure tetragonal phase structure. Under hydrothermal degradation conditions, due to the reaction of OH−and oxygen vacancy, the transformation of tetragonal to monoclinic occurred, furthermore the fluorescence properties of the powder were altered.
