Controlled Construction of Uniform Flowerlike Lanthanide Molybdate Micro-/Nano-architectures and Photoluminescence Properties

摘要

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.
