Abstract

Several Mn²⁺ doped persistent phosphors were synthesized and their optical properties were investigated. Pink or orange phosphorescence of SrMg(SiO₃)₂:Mn,Dy and (Sr,Ca)Mg(SiO₃) ₂:Mn,Dy was found to last for more than 10 minutes. Eu²⁺ presents efficient luminescence in the host SrMg(SiO₃)₂. When Eu²⁺ ions are co-doped with Mn²⁺ and Dy³⁺ into the silicate, as SrMg(SiO₃)₂:Mn,Eu,Dy, the phosphorescence is dominated by the blue emission from Eu²⁺ and the red emission from Mn²⁺ is absent. This can be explained by the assumption that the Mn²⁺ ions are not effective in trapping the excited electrons. In addition, red phosphorescence of Zn₂P ₂O₇:Mn,Cu with the peak at 627 nm was also observed.

When Eu2+ ions are co-doped with Mn2+ and Dy3+ into the silicate, as SrMg(SiO3)2:Mn,Eu,Dy, the phosphorescence is dominated by the blue emission from Eu2+ and the red emission from Mn2+ is absent. This can be explained by the assumption that the Mn2+ ions are not effective in trapping the excited electrons.
