Abstract

We investigated the persistent luminescence in europium-doped LiBaPO4. The persistent phosphors were synthesized via solid-state reaction method under mild reducing atmosphere. Its properties were investigated by x-ray diffraction, diffuse reflectance, photoluminescence, persistent luminescence, and thermoluminescence spectra. Under UV irradiation, broad-band persistent luminescence peaked at ∼470 nm was observed in the phosphors at room temperature. The effects of Eu2+ concentration on the persistent luminescence of LiBaPO4:Eu2+ were discussed. An energy level scheme was constructed to convey reasonable trapping and detrapping processes in the material.
