摘要

A novel blue light-emitting phosphor, Eu2+-doped magnesium strontium aluminate (MgSrAl10O17:Eu2+), for plasma display panel (PDP) application was developed. X-ray diffraction (XRD) patterns disclosed that the phosphor annealed at 1500 degrees C for 5 h was a pure MgSrAl10O17 phase. Field emission scanning electron microscopy (FE-SEM) images showed the particle size of the phosphor was less than 3 mu m. The phosphor shows strong and broad blue emission under vacuum ultraviolet (VUV) light excitation. After baking at 400-600 degrees C and irradiation with VUV light for 300 h, the phosphor still keep excellent VUV luminescence properties exhibiting good stability against high temperature baking and VUV irradiation. The decay time was short as 1.09 mu s and the quantum yield was high to 0.77 +/- 0.02. All the characteristics indicated that MgSrAl10O17:Eu2+ would be a promising blue phosphor for PDP application.
