solid solution microcrystallines were synthesized by hydrothermal method. The structure
morphology and photoluminescent properties of the microcrystallines were studied by X-ray powder diffraction (XRD)
scanning electron microscopy (SEM) and fluorescence analysis (FA). XRD results show that NaEu(MoO
