Synthesis and tunable luminescence properties of monodispersed sphere-like CaWO4 and CaWO4:Mo/Eu, Tb

► We have synthesized monodispersed CaWO4 and CaWO4:Mo/Eu, Tb microspheres. ► Doping proper amount of Mo into CaWO4 micropheres can extend the excitation range. ► We have tuned the color by varying the relative content of Eu to Tb in the host.
