Abstract

Sr(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)

Fourier transform infrared spectroscopy(FT-IR)

scanning electron microscopy (SEM)

and fluorescence analysis (FA)

respectively. The XRD and FT-IR results confirm that the Sr(MoO

)

(WO

)

microcrystallines are all typical scheelite structure with tetragonal symmetry. The SEM results show that the obtained phosphors are uniform spherical-like particles with smooth surface. Under the excitation of 275 nm ultraviolet radiation

the emission intensity in 350 nm decreases with the increasing of

while 470 nm emission intensity increases with the increasing of
