Abstract

NaEu(MoO

)

(WO

)

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

)

(WO

)

microcrystallines are all typical scheelite structure with tetragonal symmetry. SEM measurements reveal that the phosphors are rice-like particles. The fluorescence analysis (FA) results reveal that the characteristic emission peak of

(

= Mo

W) complex ion appears from 370 to 386 nm

and blue shifts with the increasing of

. Moreover

the characteristic emission peaks located at 592 nm and 614 nm of Eu

all appear obviously

and the intensity gradually increases with the increasing of
