Abstract

The synthesis of Sr_1-xBa_xAl₂O ₄:Eu²⁺ (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 SrAl₂O ₄ was obtained by sintering the mixtures of SrCO₃, BaCO₃, Eu₂O₃, Al₂O₃ and 3wt% B₂O₃ 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 Sr_1-xBa_xAl₂O₄:Eu ²⁺ was found at 1400°C. Substitution of Ba about 0.2mol in SrAl₂O₄:Eu²⁺ enhanced the photoluminescence and long-phosphorescence.
