A novel white-bluish emitting phosphor of Ba_0.49Sr_0.49)_2-B₂P₂O₁₀:0.02Eu²⁺is synthesized by the solid state reaction. Ba_0.49Sr_0.49)_2-B₂P₂O₁₀:0.02Eu²⁺can be effectively excited by 370 nm ultraviolet (UV) light, and exhibits two emission bands at 430 nm and 522 nm which are attributed to the d-f transitions of the Eu2+ ions in two different cation sites in the host lattices. And the chromaticity coordinate of Ba_0.49Sr_0.49)_2-B₂P₂O₁₀:0.02Eu²⁺phosphor is (0.29, 0.25).
