초록

We applied the spray pyrolysis technique to prepare Mn-doped $BaMgAl_{10}O_{17}$ (BAM) particles with high photoluminescence, which could be used in the plasma display device as a green phosphor. Several preparation conditions were investigated in order to tail the vacuum ultraviolet (VUV) characteristics. Some portions of barium were replaced with strontium to improve the luminescent intensity of BAM:Mn particles under VUV excitation. The content of Mn and Sr was optimized to obtain high luminescent efficiency under VUV excitation. Finally, the optimized BAM:Mn green particles showed higher photoluminescence intensity than that of commercial $Zn_2SiO_4$ and comparable with commercial barium-aluminate phosphor.
