摘要：

Ba5(PO4)3Cl:Eu2+ phosphors were synthesized by a high temperature solid state reaction with Eu2O3, NH4H2PO4, BaCl2·2H2O, and BaCO3 as the raw materials. The crystal structure and luminescent properties of the samples were analyzed by the X-ray diffraction and the fluorescence spectrophotometer. The results show that Ba5(PO4)3Cl:Eu2+ phosphors synthesized are pure, the excitation spectrum contains a broad band in a range of 245~425 nm, and the emission band locats in 400~500 nm, indicating Ba5(PO4)3Cl:Eu2+ is a blue phosphor under near UV excitation. Eu2+ concentration affects the luminescent intensity of Ba5(PO4)3Cl:Eu2+ phosphor synthesized seriously. The emission intensity firstly increases and then decreases as Eu2+ content increases. The emission intensity reaches the maximum when the doped Eu2+ concentration is 3%.
