Characterization and Photoluminescence of Sr₂B₂O₅:Eu³⁺, Na⁺Red Phosphor

Abstract:

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→⁷F₂transition 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.
