In this study, green barium strontium silicate phosphor (BaSrSiO4:Eu3+, Eu2+) was synthesized using a solid-state reaction method in air and reducing atmosphere. Investigation of the firing temperature indicates that a single phase of BaSrSiO4 is formed when the firing temperature is higher than 1400 oC. The effect of firing temperature and doping concentration on luminescent properties are investigated. The light-emitting property was the best when the molar content of Eu2O3 was 0.025 mol. Also, the luminescent brightness of the BaSrSiO4 fluorescent substance was the best when the particle size of the barium was 0.5 μm. BaSrSiO4 phosphors exhibit the typical green luminescent properties of Eu3+ and Eu2+. The characteristics of the synthesized BaSrSiO4:Eu3+, Eu2+ phosphor were investigated using X-ray diffraction (XRD) and scanning electron microscopy. The maximum emission band of the BaSrSiO4:Eu3+, Eu2+ was 520 nm.
