| Abstract: | Controlled synthesis of hierarchical Barium molybdate (BaMoO4) nanostructures with different morphologies, such as peanut-like, cube-like and flower-like, was successfully achieved in aqueous solution at room temperature. The obtained products were characterized by a scanning electron microscope (SEM) and an X-ray power diffractometer (XRD). The morphologies of the obtained products were found to be greatly dependent on reaction time, EDTA concentration and the Ba2+]/MoO42−] ratio. This controllable method could be readily extended to produce hierarchical Barium tungstate (BaWO4) nanostructures with peanut-like, dumbbell-like, sphere-like and flower-like morphologies. The photoluminescence (PL) properties of the obtained BaMoO4 and BaWO4 nanostructures exhibited strong dependence on the morphologies and sizes, respectively. |
