N2 - Blue-emitting (K 1-xNa x)Mg 4(PO 4)3:Eu 2+ phosphors were synthesized through a conventional solid-state reaction method, and their photoluminescence properties were characterized. These phosphors exhibited the typical emission band assigned to the transition from 4f65d1 to 4f7 of Eu2+, and the emission intensity was effectively enhanced by Na +-doping into the host lattice. The highest blue emission peak intensity was obtained for (K 0.65Na 0.35)Mg 4(PO 4)3:1 mol%Eu2+, where the relative emission peak intensity was 33% of that for the commercial blue-emitting BaMgAl 10O 17:10 mol%Eu 2+ phosphor. In addition, these phosphors have excellent thermal stability in the temperature quenching effect.
