摘要：

Uniform ordered spherical YVO4:Eu3+ luminescent materials and coating GdVO4 on their surface were synthesized by hydrothermal method. XRD patterns show that the samples before and after coated are all tetragonal zircon structured YVO4, and the crystal grows well. MR spectra present the V-O, Y-O stretching vibration absorption peaks. SEM images indicate that the samples before and after coated are all in ordered uniform spherical shape. XPS analysis further proves that the YVO4:Eu3+@GdVO4 core-shell structure has been formed. Photoluminescence spectra show that the emission intensities of YVO4:Eu3+@GdVO4 core-shell composite particles are higher than that of the YVO4:Eu3+ core particles.
