Article Preview

YVO4:Eu3+,Ln (Ln = Bi3+, La3+, Li+) red phosphors were prepared by combustion synthesis, and effect of the Bi3+, La3+, Li+ doping ions on luminescence properties was studied. After doping with Bi3+, the emission intensity, excited by 322nm UV, decreased, but the absorption at 365nm was effectively enhanced; the brightness was increased by doping with La3+ or Li+, and the emission intensity at 619nm for YVO4:0.05Eu3+,0.15 Li+, excitation at 322nm, was about 160% of that for YVO4:0.05Eu3+.
