Abstract

BaMgAl₁₀O₁₇:Eu²⁺ (BAM) is one kind of commercial blue phosphor in fluorescent lamps, because of its efficient blue emission. A serial of phosphors BaMgAl₁₀O₁₇:0.1Eu²⁺ doped different H₃BO₃ concentration were prepared by solid-state reaction technique, and their photoluminescent properties were investigated. The introduction of H₃BO₃ broadens the excitation band of the phosphor BAM around 400 nm and enhances the emission intensity under 400 nm light excitation. The emission of the phosphor BAM doped with 6% H₃BO₃ has optimum blue emission, with good CIE (Commission Internationale de l'Eclairage, International Commission on Illumination) chromaticity coordinates x = 0.151, y = 0.058. Hence, the phosphor can be applied in fabrication of near-UV LED excited white light-emitting diode (LED).
