| Abstract | CaWO4:Dyx 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 diffraction(XRD), scanning electron micrograph(SEM) and fluorescence analysis(FA). Our results show that the CaWO4:Dyx microcrystallines were scheelite structure with tetragonal symmetry. The doping of Dy inhibits the grain growth,decreases the intrinsic emission of WO4 complex ions and enhances the peeks located at 480nm and 575nm of Dy ion, giving the maximum at x =0.01. The abtained CaWO4:Dy0.01 microcrystalline is a promising phosphor and its grain size is about 4μm. |
