Abstract

Fine-sized BaMgAl10O17:Eu2+ phosphor powders with plate-like morphology were prepared by spray pyrolysis process. The effects of ratio of BaF2 and Ba(NO3)2 used as the source materials of Ba component on the morphological and optical properties of the BaMgAl10O17:Eu2+ phosphor powders were investigated. BaF2 was used as the flux material as well as the source material of Ba component. The phosphor powders prepared from the spray solution with the same mole concentrations of BaF2 and Ba(NO3)2 had fine size, plate-like morphology and narrow size distribution. The addition of BaF2 as the source material of Ba component increased the photoluminescence intensities of the phosphor powders. The phosphor powders prepared from the spray solution with the ratios of BaF2 and Ba(NO3)2 larger than 1 had the similar photoluminescence intensities to that of the commercial product.
