Abstract

In plasma display panel, the barium magnesium aluminate (BAM) phosphor has been conventially adopted as a blue-emitting component due to its availability and high quantum efficiency. Attempt had done to prepare BAM in addition with gallium. In this paper, we used combustion synthesis for preparation for barium based phosphor. Combustion synthesis furnishes a quick method for preparing these phosphors. Photoluminescence (PL) characteristics of all these compounds were studied by using a Hitachi F-4000 spectrofluorimeter, at room temperature, using 1.5nm spectral slit width in the range of 200-700nm.
