26.4: Invited Paper: Recent Development of Blue Phosphors for PDP Application

As a blue‐emitting phosphor, only BaMgAl10O17: Eu2+ (BAM) is practically being used in plasma display panel (PDP). However, BAM deteriorates seriously during the panel processing and operation, resulting in a loss of efficiency and color purity. In this paper, the research on BAM degradation mechanism is reviewed. In addition, the current status of BAM improvements and new blue‐emitting phosphors as BAM substitution candidate is discussed for PDP application.
