Abstract

Abstract: Sr₄Al₁₄O₂₅:(Eu,Dy) phosphor materials were prepared by solid state reaction. The dependence of long persistent luminescence from Sr₄Al₁₄O₂₅:(Eu²⁺, Dy³⁺) on the amounts of H₃BO₃, the solid state reaction temperature, and the contents of Eu were studied. It was found that the addition of H₃BO₃as the flux agent was critical for the formation of the blue-green emitting Sr₄Al₁₄O₂₅ phase. Sr₄Al₁₄O₂₅ phosphors with persistent luminescence of 490 nm and afterglow time more than 24 h was obtained for the sample prepared at 1400℃ with the doping amounts of H₃BO₃ of 10at% and Eu/Al atomic ratio of 0.03, respectively. Furthermore, the dependence of persistent luminescence intensity on Eu content indicates that the persistent luminescence process is mainly controlled by the electron transition rate from deep traps to Eu²⁺ levels.
