چکیده انگلیسی
Dense BaMgAl10O17:Eu2+ phosphor particles with a spherical shape have been synthesized through spray pyrolysis method by using a novel precursor solution. In order to fabricate dense phosphor particles, the spray solution was prepared by adding barium, magnesium and europium nitrates into the basic aluminum nitrate solution, which is synthesized from Al metal and aluminum nitrate. Also, the Al concentration in the spray solution was optimized on the basis of the relative density and the emission intensity of the obtained phosphor particles. Phosphor particles prepared from this spray solution have exhibited completely spherical shape and filled morphology, while that prepared from general nitrates precursor solution have had hollow and irregular structure. As the result, the prepared BaMgAl10O17:Eu2+ phosphor particles have shown the stronger emission intensity compared to the commercial BaMgAl10O17:Eu2+.
