phosphors were synthesized by co-precipitation reaction.The X-ray powder diffraction

photoluminescence excitation spectra and luminescence decay were measured.With increasing the amount of vanadate group
the excitation band shifts to the lower energy that satisfies the application demand for the LED phosphors.Tm

phosphors were calculated.It was found that the chromaticity coordinates are dependent on both the ratios of P/V and Tm/Dy.This phosphor system with proper composition and dopants may be a promising phosphor candidate for white light emitting LED applications.
