Abstract

The VUV characteristics of BaMgAl₁₀O₁₇:Eu²⁺ phosphor particles prepared by an ultrasonic spray pyrolysis were compared with those of commercial product. The precursor effect on the morphology and brightness of phosphor particles was investigated in spray pyrolysis. The phosphor particles were prepared from 24 combinations of barium, magnesium, and aluminum component precursors composing host material. The precursor types strongly affected the morphology and luminescence characteristics of BAM phosphor particles. The BAM phosphor particles posttreated at above 1250 °C had higher brightness than that of commercial product. The maximum brightness of particles obtained at 1350 °C from nitrate precursors was 109% that of commercial product. This optimum posttreatment temperature in spray pyrolysis is lower than that of conventional solid-state reaction method.
