摘　　要：A novel white-bluish emitting phosphor of (Ba0.49Sr0.49)2B2P2O10:0.02Eu2+ is synthesized by the solid state reaction. (Ba0.49Sr0.49)2B2P2O10:0.02Eu2+ 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 (Ba0.49Sr0.49)2B2P2O10:0.02Eu2+ phosphor is (0.29, 0.25).A novel white-bluish emitting phosphor of （Ba0.49Sr0.49）2B2P2O10：0.02Eu2＋ is synthesized by the solid state reaction. （Ba0.49Sr0.49）2B2P2O10：0.02Eu2＋ 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 （Ba0.49Sr0.49）2B2P2O10：0.02Eu2＋ phosphor is （0.29, 0.25）.
