Abstract

In plasma display panel, the Eu²⁺ activated Barium Magnesium Aluminate (BAM) phosphor has been conventionally adapted as a blue emitting component in many displays due to its availability and high (>98%) quantum efficiency. BaMgAl₁₀O₁₇:Eu²⁺ (BAM) phosphor was synthesized in two steps using auto-combustion method followed by sintering in reducing atmosphere. The X-ray diffraction data confirms the high crystallinity and hexagonal structure of BAM nanophosphor, suggesting its potential for optoelectronic devices. Scanning electron microscopy reveals a uniform rectangular morphology, indicating a consistent and controlled synthesis. The study emphasizes the promising applications of BAM nanophosphor, particularly in enhancing color purity for plasma display panel screens, contributing valuable insights to improve nanophosphor performance in electronic displays.
