Uniform and well-dispersed SrMoO4 hierarchical microspheres have been synthesized via a facile citrate-assisted hydrothermal approach. The as-obtained particles are non-aggregated with narrow size distribution and are composed of closely packed nanoparticles. The reaction conditions, including trisodium citrate additive, pH value of the initial solution, as well as reaction temperature and time, have great effect on the particle size and morphology of the products. The as-synthesized SrMoO4:Ln(3+) (Ln=Eu, Tb, Dy, and Sm) samples show intense characteristic emissions with different colors under ultraviolet excitation, which may find potential applications in the fields of fluorescent lamps, color displays, and light-emitting diodes (LEDs).
