Abstract

The $Eu^{3+}$ doped $Y(P_x,V_{1-x})O_4$ (0 ${\leq}$ x ${\leq}$ 1) phosphors were synthesized by solid-state and impregnation method and investigated as potential red-emitting phosphors for a plasma display panel(PDP). The optimal substitution proportion of P for V was determined to be 60 mol%, for $Y(P_x,V_{1-x})O_4$ doped with 8 mol% $Eu^{3+}$. The VUV PL spectra and SEM for the synthesized phosphors were measured and compared against those of a commercial red-emission phosphor. The $Y(P_x,V_{1-x})O_4$:$Eu^{3+}$ phosphors exhibited strong red at around 592, 618 and 698 nm. The emission intensity and particle size of the phosphors were controlled by preparation conditions.
