Abstract

Fine-sized BaMgAl10O17:Eu2+ (BAM:Eu) phosphor powders with regular morphology were prepared by flux-assisted spray pyrolysis. The precursor powders with hollow structure and large size obtained by spray pyrolysis were mixed with aluminum fluoride flux. The post-treated BAM:Eu phosphor powders had fine sizes, narrow size distributions, and plate-like morphologies without milling process. The mean size of the BAM:Eu phosphor powders obtained from the optimum amount of aluminum fluoride flux was 1.1μm. The photoluminescence intensity of the phosphor powders obtained from the precursor powders without flux was 84% of that of the commercial phosphor powders. On the other hand, the photoluminescence intensities of the phosphor powders obtained from the precursor powders with 3 and 5 mass% aluminum fluoride flux were each 90% and 93 % of that of the commercial phosphor powders.
