Facile Synthesis and Luminescent Properties of Novel Flowerlike BaMoO4 Nanostructures by a Simple Hydrothermal Route

Flowerlike nanostructures of metals or compounds show interesting physical properties. In this article, novel flowerlike BaMoO4 nanostructures were successfully synthesized via a simple hydrothermal route. The as-synthesized products were studied by X-ray powder diffraction, scanning electron microscopy, Brunauer-Emmett-Teller, and transmission electron microscopy. The results showed that the nucleation and growth of the flowerlike nanostructures were governed by a nucleation-dissolution-recrystallization growth mechanism. The formation of the three-dimensional flowerlike BaMoO4 nanostructures was strongly dependent on the concentration of cetyltrimethylammonium bromide (CTAB). Control experiments were carried out to investigate various influencing factors on the morphology of the products. Different morphologies of BaMoO4 nanostructures were synthesized through adjusting CTAB concentration, temperature, and the volume ratio of N,N-dimethylacetamide to H2O. Luminescent properties of the flowerlike and multilayered BaMoO4 nanostructures consisting of nanosheets were studied, and the flowerlike BaMoO4 nanostructures showed a strong green emission, indicating that the flowerlike BaMoO4 nanostructures have great potential to be applied in luminescent areas.
