Fabrication and luminescence properties of Y2SiWO8 : Dy3+ phosphors via sol-gel process

(YSiWO8)-Si-2:Dy3+ phosphors were prepared through a sol-gel process. XRD and photoluminespectra were used to characterize the resulting phosphors. The results indicated that the phosphors crystallized completely at 1000 degrees C. In Y2SiWO8:Dy3+ phosphors, the Dy3+ showed its characteristic yellow emission at 483nm (F-4(9/2)-H-6(5/2)) and 575nm (F-4(9/2)-H-6(13/2)) upon excitation into 275nm.
