Effect of Er³⁺ and Nd³⁺ doping on the luminescent properties of BaMgAl₁₀O₁₇:Eu phosphor

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 Er³⁺ increases effectively. When Nd³⁺ 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.
