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).
