在表面活性剂十二烷基硫酸钠(SDS)的作用下,采用温和的水热方法,成功制备了Eu掺杂的花瓣状La2(MoO4)3∶Eu纳米微结构.这些形貌新颖的微米绒球的直径约3μm,由厚度30nm左右的纳米片次级结构单元自组装构筑而成,分散性良好,形貌规整、大小均一.通过XRD、SEM、TEM测试技术,研究了形貌的形成机理.由于具有良好的结晶度,这些花瓣状La2(MoO4)3∶Eu纳米微结构显示出良好的发光性能.
Three-dimensional flowerlike europium doped lanthanide molybdate (La2 (MoO4)3: Eu) micro-architectures, which exhibit efficient photoluminescence, have been successfully synthesized via a facile hydrothermal process in the presence of the surfactant sodium dodecylsulfate (shortened title: SDS). These microspheres are well dispersed and have a uniform diameter of about 3μm, and are composed of secondary structures-nanoflakes with thickness of about 30nm. The structure was characterized by XRD, SEM and TEM, and the possible action mechanism of the surfactant is preliminarily investigated. These La2(MoO4)3: Eu microspheres show efficient photoluminescence which is associated with the well crystallized structures of the micro-architectures.
