摘要: A novel white-bluish emitting phosphor of (Ba0.49Sr0.49)2B2P2O10:0.02Eu2+ is synthesized by the solid state reaction. can be effectively excited 370 nm ultraviolet (UV) light, and exhibits two emission bands at 430 522 which are attributed to d-f transitions Eu2+ ions in different cation sites host lattices. And chromaticity coordinate (0.29, 0.25).
