BaMgAl10O17:Eu blue phosphors were synthesized and the effect of doping er3+ and Nd3+ ions in the phosphor on the luminescent properties was investigated. When the content of Er3+ and Nd3+ ions is small, the phosphor remains single phase and the luminescent intensity of Eu2+ increases effectively. When Er3+ is doped, the shape of the excitation spectrum of the phosphor in the UV (ultraviolet) region remains unchanged. As Nd3+ is doped in the phosphor, the location and intensity of the two excitation peaks, and the emission intensity ratio excited by corresponding UV change dramatically owing to the alternation of crystal field splitting and level barycenter of 4f65d configuration of Eu2+ ion.
