复合助熔剂对BaMgAl10O17:Eu2+蓝色荧光粉晶体结构、颗粒形貌及发光性能的影响

摘要采用先烧结后还原的高温固相法制备了BaMgAl₁₀O₁₇:Eu²⁺（BAM）蓝色荧光粉,研究了H₃BO₃+BaF₂、H₃BO₃+AlF₃、BaF₂+AlF₃３种不同组合的复合助熔剂对BAM蓝色荧光粉的物相纯度、颗粒形貌及发光性能的影响。结果表明：以H₃BO₃+BaF₂为复合助熔剂的蓝粉与其它2种复合助熔剂制备的样品相比在提高BAM物相纯度、颗粒形貌貌以及发光性能方面具有更好的效果，其性能已非常接近市场上某公司生产的商业蓝粉。

Abstract： BaMgAl₁₀O₁₇:Eu²⁺（BAM）blue phosphors were synthesized by high temperature solid state reaction. The influences of composite fluxes, such as H₃BO₃+BaF₂, H₃BO₃+AlF₃and BaF₂+AlF₃, on phase purity, particle morphology and luminescent properties of blue phosphors were investigated. The results indicated that samples fluxed by H₃BO₃+BaF₂had better performance to form pure phase, particle size and particle shape and luminescence intensities than those fluxed by H₃BO₃+AlF₃ and BaF₂+AlF₃, the performance is close to that of commercial blue phosphor of a company.
