摘要：

In this work, a red long-lasting phosphor: MgSiO3:Eu2+, Dy3+, Mn2+ was prepared by sol-gel method. The XRD pattern of this phosphor is indexed on a proto-enstatite structure (JCPDS No. 11-0273). Its red long-lasting phosphorescence was confirmed and attributed to the Mn2+ emission. In MgSiO3:Eu2+, Dy3+, Mn2+, the functions of co-doped Eu2+ and Dy3+ ions are affirmed as sensitizers and trap centers, respectively. Further TL study was taken on the trap centers introduced by Dy3+, including fitting of trap depths and frequency factors. Moreover, a long-lasting phosphorescence model of MgSiO3:Eu2+, Dy3+, Mn2+ was suggested, (C) 2007 Elsevier B.V. All rights reserved.
