Abstract

(Y0.5Gd0.5)0.94-x(V0.25P0.75)O4:Eu0.06,Lix (0≤x≤0.02) red emitting phosphor powder were synthesized via the solution combustion process and the luminescent intensity under vacuum ultraviolet VUV (147 nm) excitation was investigated by co-doping Li+ content, Y/Gd molar ration. According to the X-ray diffraction (XRD) results (Y0.5Gd0.5)0.94-x(V0.25P0.75)O4:Eu0.06,Lix phosphors had the tetragonal structure. Photoluminescence (PL) results have shown strongest red emission at 620 nm, which originated from the 5D0 → 7F2 transition of Eu3+ ion, for the (Y0.5Gd0.5)0.925(V0.25P0.75)O4:Eu0.06,Li0.015 phosphor. The addition of Li+ was greatly improved the photoluminescence properties of (Y0.5Gd0.5)0.94(V0.25P0.75)O4:Eu0.06 phosphors due to an effective energy transfer between Eu3+ ion and Li+ ion.
