Abstract

YVO

:Eu

nanoparticles of about 8 nm were synthesized by precipitation reactions and coated with SiO

by a reverse microemulsion method. Powder X-ray diffraction (XRD) patterns indicate that these nanoparticles are purely tetragonal phase. Transmission electron microscope (TEM) images show that YVO

:Eu

nanoparticles are successfully coated with silica to form core-shell structured nanocomposites. The thicknesses of SiO

shells can be altered by changing the volume of tetraethoxysilane (TEOS) used in the reaction. The ultraviolet-visible (UV-Vis) absorption spectra of YVO

:Eu

@SiO

nanocomposites agree well with that of the YVO

:Eu

nanoparticles colloid. Both the excitation and emission spectra are the same for YVO

:Eu

nanoparticles and the nanocomposites. With the increasing of the thickness of SiO

shell

the intensity ratio of

decreases

indicating that SiO

shells can increase the local symmetry of Eu

. All samples can emit bright red light under ultraviolet irradiation. The photoluminescence quantum yield decreases after SiO

coating. With the increasing of the thickness of SiO

shell

the photoluminescence quantum yield becomes lower and lower.
