Abstract

Persistent phosphorescence of SrMg(SiO₃)₂:Mn,Dy was found to present two broad bands in the red and blue regions, respectively, accompanied by a 4f→4f emission from Dy³⁺. The red band was attributed to the Mn²⁺ emission, and the blue one was due to the defects induced by Dy³⁺. The phosphorescence of singly doped sample SrMg(SiO₃)₂:Dy also exhibits the blue band and Dy³⁺ emissions, which enable one to optically investigate the trapping mechanism in the Dy co-doped phosphors. A comparison of Mn²⁺ ions with the co-doped Eu²⁺ ions in phosphorescence emission was made to examine the behavior of Mn²⁺ ions in binding the delocalized carriers for the subsequent phosphorescent recombination. A reversed detrapping process was proposed to explain the phosphorescent properties of SrMg(SiO₃)₂:Mn,Dy.
