摘　　要：提出了以流变相-先驱物法制备稀土复合氧化物ZnEu2O4的软化学方法。首先用流变相法合成草酸盐先驱物,然后用DTA和TG研究了先驱物在空气中的热分解过程;用X射线粉末衍射和IR光谱表征了固体产物;最后测定了固体产物的固体紫外-可见吸收及荧光光谱。结果表明,ZnEu2O4为立方结构,其主要荧光发射区在波长为608.0nm处。流变相-先驱物法为制备稀土复合氧化物提供了一种简单、可行、有效的方法。A soft chemical route is proposed for the preparation of ZnEu2 04 by rheological phase-precursor reaction method. Firstly, the oxalate precursor is synthesized by rheological phase reaction, and then thermal decomposition of oxalate precursor in air atmosphere is studied by DTA and TG. The solid product of thermal decomposition is characterized by XRD and IR, and finally the solid state UV-Vis absorption spectrum and the fluorescence spectrum of ZnEu204 are measured. The results reveal that the ZnEu204 is a cubic structure and its main fluorescence emission area is around 608. 0nm. The theological phase-precursor reaction method provides a simple, practicable and effective route for the synthesis of rare earth oxides.
