Abstract

Ba2Mg(BO3)2:Eu2+ phosphors incorporated with two different sensitizers, Mn2+ or Ce3+, were prepared and their emission properties, especially for color purity and thermal stability, were investigated thoroughly. The overall emission property induced by the Eu2+ ion and the resultant thermal behavior were strongly dependent on the type of codoped sensitizer ions, Mn2+ or Ce3+. Intense red emission peaking at 620 nm was obtained upon 370 nm excitation of the Mn2+-sensitized phosphor and the resultant light-emitting diode lamps using the given phosphor exhibited a more reddish emission with chromaticity coordinates of (0.602, 0.340). Thus, we can meet the purpose of illuminating elements by designing the proper chemical composition of the Eu2+-activated Ba2Mg(BO3)2 phosphor using different sensitizers: a more reddish emitting Mn2+-sensitized one for backlight units and a bright yellow-emitting Ce3+-sensitized one for solid-state lightings.
