CaWO4:Dy3+ x solid solution microcrystallines were synthesized by hydrothermal method; the crystal structure, surface morphology and room temperature photoluminescence properties of the microcrystallines were investigated by through X-ray diffractionXRD, scanning electron micrographSEM and fluorescence analysisFA. Our results show that the CaWO4:Dy3+ x microcrystallines were scheelite structure with tetragonal symmetry. The doping of Dy3+ inhibits the grain growth,decreases the intrinsic emission of WO2- 4 complex ions and enhances the peeks located at 480nm and 575nm of Dy3+ ion, giving the maximum at x =0.01. The abtained CaWO4:Dy3+ 0.01 microcrystalline is a promising phosphor and its grain size is about 4μm.
