    By co-doping the P5+ ions into Ba3SiO5:Eu2+, we synthesized new orange persistent phosphor using cellulose assisted liquid phase precursor (LPP) method. The emission spectra showed a typically broad orange emission band centered at 575 nm attributed to the 4f65d1 → 4f7 transition of Eu2+ ions under 400 nm excitation source. The persistent luminescence property of Eu2+ doped Ba3SiO5 orange phosphor was enhanced by co-doping non-equivalent phosphorus ions into silicon sites. This enhancement can be explained by formation of the trapping center due to the charge compenstation. Consequently, the afterglow decay exhibited an orange emission for more than 5 min after irradiation at under 365 nm for 1 min.
