title: Well-defined strontium tungstate hierarchical microspheres: synthesis and photoluminescence properties.
abstract: Uniform and well-dispersed SrWO4 microspheres have been successfully synthesized through a hydrothermal method by using trisodium citrate and SDS as surfactants. XRD and SEM results demonstrate that the as-synthesized SrWO4 particles are high purity well crystallized and exhibit a relatively uniform spherical morphology. The as-obtained SrWO4:Ln3+ (Ln = Tb, Eu, Dy, and Sm) microspheres show intense light emissions with different colors coming from different Ln3+ ions under ultraviolet excitation, which might find potential applications in the fields such as light emitting phosphors, advanced flat panel displays, and light-emitting diodes (LEDs).
