Broad Red Emission with Ultraviolet Excitation in Pr³⁺ Doped MgAl₂O₄ Phosphors

Abstract:

The broad strong red emission in Pr³⁺ doped MgAl₂O₄ phosphor powders have been synthesized by conventional solid state reaction in air. The temperature dependence of particle size and structural phase were investigated. The intense red emission of the phosphors is observed under 250-350 nm excitation, which cover the spectrum of Ultraviolet. The optimal emission intensity was obtained when Pr doping level was 0.002mol. The lifetime decay curves with different concentrations and a possible mechanism were also studied.
