NaBa12B7O21F4:xEu(3+) phosphors, where 0 < x <= 0.16, were obtained through the high temperature solid phase reaction method. The phosphors showed significant red fluorescence emission resulting from the dominant D-5(0)-> F-7(2) transitions. The optimum doping concentration of Eu3+ ions in the NaBa(12)B(7)O(21)F(4 & nbsp;)matrix were estimated to be 14 mol%. The phenomenon of concentration quenching was researched, and the concentration quenching of NaBa12B7O21F4:xEu(3+) phosphors maybe caused by the exchanging interaction of Eu3+ ions. Moreover, it was found that the optimal-component NaBa12B7O21F4:xEu(3+) phosphor showed high absolute luminescence quantum efficiency and had a millisecond fluorescence lifetime.
