Abstract

(Zn

)

GeO

:Mn

0.25) green phosphors were synthesized by the conventional solid-state reaction

and the effect of Mg incorporation on photoluminescence (PL) and long-lasting phosphorescence (LLP) characteristics of Zn

GeO

:Mn

was systematically studied. The emission spectrum shows a broad emission band centered at 533 nm

which can be assigned to the

(

S) transitions of Mn

ion. The emission intensity can be increased by the resonant transfer from a subbandgap state in the host to Mn

and the PLE spectra of (Zn

)

GeO

:Mn

exhibit a blue shift with the increasing of Mg concentration. Thermoluminescence (TL) spectra indicate that the introduction of Mg into the host deepened the Vo traps

resulting in the enhanced phosphorescence of Mn

. The possible mechanism of the PL and LLP was discussed based on the PL and TL results.
