Abstract:
Hierarchical europium oxalate Eu2(C2O4)3·10H2O micro-particles were synthesized through a simple precipitation method at room temperature in present of trisodium citrate. The prod-ucts were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, and photoluminescence. The possible formation mechanism of the hierarchical europium oxalate Eu2(C2O4)3·10H2O micro-particles was discussed.

摘要:
在室温条件下, 以柠檬酸钠为辅助剂, 通过简单沉淀法合成了草酸铕Eu2(C2O4)3·10H2O微米层状颗粒. 应用X射线衍射、X射线电子能谱、场发射扫描电子显微镜、光致发光光谱对Eu2(C2O4)3·10H2O结构与性能进行了表征. 讨论了草酸铕微米层状颗粒可能的形成机理.
