Abstract

A bluish green light-emitting phosphor, Eu²⁺-doped barium aluminate (BaAl₂O₄:Eu²⁺), for plasma display panel (PDP) application was developed. X-ray diffraction (XRD) patterns disclosed that the phosphor annealed at 1300 °C for 5 h was a pure BaAl₂O₄ phase. Field emission scanning electron microscopy (FE-SEM) image showed the particle size of the phosphor was less than 2 μm. The phosphor shows strong and broad bluish green emission under vacuum ultraviolet (VUV) light excitation. After baking at 400-600 °C and irradiation with VUV light for 300 h, the phosphor still keeps excellent VUV luminescence properties, exhibiting good stability against high temperature baking and VUV irradiation. The decay time was short as 0.721 μs and the quantum yield was high to 0.54 ± 0.02 under near ultraviolet band. All the characteristics indicated that BaAl₂O₄:Eu²⁺ would be a potential phosphor for PDP application.
