Eu2+-doped Rb2Ba3P4O14 phosphors were synthesized in a single phase form by a conventional solid state reaction method and their optical properties were characterized. These phosphors showed broad optical absorption bands that can cover the UV and near-UV region, and exhibited a narrow deep-blue emission and broad reddish-yellow emission with peaks at 423 nm and 550 nm, respectively. The highest reddish-yellow emission intensity was obtained for Rb2(Ba0.99Eu0.01)3P4O14.
