Uniform and well-dispersed barium molybdate (BaMoO4) hierarchical microspheres and microflowers have been successfully synthesized via a hydrothermal route by using sodium dodecyl benzenesulfonate (SDBS) as surfactant. The reaction conditions, including SDBS additive, pH value of the initial solution, as well as reaction temperature, have great effect on the size and morphology of the BaMoO4 products. The possible formation process of the BaMoO4 microspheres has been investigated by time-dependent experiments. The as-synthesized BaMoO4:Ln(3+) (Ln = Eu, Tb, Dy, and Sm) phosphors show intense characteristic red, green, green-yellow, and orange-red emissions under ultraviolet light excitation, which might find potential applications in the fields of light emitting phosphors, advanced flat panel displays, and light-emitting diodes (LEDs).
