Photoluminescence Properties of Ba-Substituted SrAl2O4:Eu Phosphor


Article Preview

The synthesis of Sr1-XBaXAl2O4 :Eu 2+ (x = 0, 0.1, 0.2 and 0.3 mol) phosphor and its properties of photoluminescence and long-phosphorescence were investigated as a function of sintering condition. The single phase of SrAl2O4 was obtained by sintering the mixtures of SrCO3, BaCO3, Eu2 O3, Al2O3 and 3wt% B2 O3 powders over 1100°C in Ar/H2 atmosphere. Stuctural properties were analyzed by a X-ray diffractometer, microstructural properties by a SEM, and photoluminescent properties by a PL measuring system. The optimum sintering condition for the long-phosphorescent phosphor of Sr1-XBaXAl2O4:Eu2+ was found at 1400 °C. Substitution of Ba about 0.2mol in SrAl2O4 :Eu 2+ enhanced the photoluminescence and long-phosphorescence.
