英文摘要	Conference Name:2nd International Conference on Insulating Materials, Material Application and Electrical Engineering, MAEE 2014. Conference Address: Nanjing, China. Time:July 26, 2014 - July 27, 2014.; Beijing Gireida Education Research Center; International Science and Education Researcher Association; VIP-Information Conference Center, China; A kind of red emitting phosphor, Sr2B2O5:Eu3+, Na+ for white light-emitting diodes (W-LED) was synthesized by high-temperature solid-state reaction method. The characterization and luminescence properties of the phosphor were investigated. It is found that this phosphor can be effectively excited by 394 nm near- ultraviolet (n-UV) light, and exhibit bright red emission centered at 613 nm corresponding to the 5D0→7F2 transition of Eu3+ ions. It is shown that the 11 mol% of Eu3+ doping concentration in Sr2B2O5:Eu3+, Na+ phosphor is optimum, and the concentration quenching occurs when the Eu3+ concentration is beyond 11 mol%. The concentration quenching mechanism can be interpreted by the dipole-dipole interaction of Eu3+ ions. The present work suggests that this novel phosphor is a kind of potential red emitting phosphor. ? (2014) Trans Tech Publications, Switzerland.
