Abstract
•Known Eu2+-activated phosphate persistent phosphors are listed.•The influence of codopants is compared with aluminates and silicates.•The concentration quenching of persistent luminescence is discussed.
Recently, as a novel class of persistent phosphors, Eu2+-activated phosphate persistent phosphors have received considerable attention. In this review, we focus on new reported phosphate persistent phosphors. Their wavelength maximum, trap filling source, optimal codopant, etc., are compared. Furthermore, the mechanism behind this phenomenon, including energy level scheme, the influence of codopant and concentration quenching are discussed.
