Abstract： Molybdate phosphors doped with rare earth ions have attracted much attention in the field of LED lighting and display because of their low synthesis temperature， excellent chemical and physical properties， good thermal stability and strong charge transfer band. In this paper， the preparation methods of molybdate with rare earth doped scheelite structure are reviewed， and the future development trend is prospected.

Keywords： scheelite molybdate; phosphor; rare earth ion; photoluminescence; preparation method
