title: Thermal stability and photoluminescence of S-doped BaMgAl10O17:Eu2+ phosphors for plasma display panels.
abstract: Sulfur-doped BaMgAl(10)O(17):Eu(2+) phosphors were synthesized by an environmentally benign synthesis reaction. The photoluminescence spectrum, the energy dispersion spectrum, powder x-ray diffraction, and decay curves were used. The photoluminescence and thermal stability were discussed. It was revealed that sulfur doping leads to an increase in luminance intensity and thermal stability. This could be due to the decrease of defects and lower electronegativity of sulfur while sulfur occupied the unstable O (1) sites. The change of trap concentration was evaluated by the decay curves. The result shows sulfur doping is expected to be potentially applicable to the industrial production of BaMgAl(10)O(17):Eu(2+) phosphors.
