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。 Eu-doped petal-like La2 (MoO4) 3: Eu nanostructures were successfully prepared by the mild hydrothermal method under the action of surfactant sodium dodecyl sulfate (SDS). These novel microsphere pompoms have a diameter of about 3 μm and are constructed by self-assembly of nanosheet secondary structural units with a thickness of about 30 nm, with good dispersibility, uniform appearance and uniform size. The formation mechanism of morphology was studied by XRD, SEM and TEM. Due to their good crystallinity, these petal-like La2 (MoO4) 3: Eu nanostructures show good luminescence properties.
