SrMoO4xWO41-x microcrystallinesx = 0-0.5 were synthesized by solid-state method.The XRD of microcrystallines showed that the crystal structure were scheelite structure with tetragonal symmetry. The surface morphology was tetragonal taper grains and the grain size of the pure SrWO4 was about 15μm. When Mo substituted for part of the W to synthesize the SrMoO40.5WO40.5 microcrystalline, its grain size reduced to 10μm and its emission peek located at 493nm and its strength was also increased than the pure SrWO4, which possesses high economic value.
