Abstract
The red light long-lasting phosphors BaMg2Si2O7: Ce3+, Mn2+, Dy3+ were synthesized by solid-state reactions under a weak reductive atmosphere. The energy transfer between Ce3+ and Mn2+ in BaMg2Si2O7 was systematically investigated. Through co-dope with Ce3+ in BaMg2Si2O7:Mn2+, Dy3+, the red phosphorescence of Mn2+ can prolong to more than 2 h. Two types of traps were existed in BaMg2Si2O7.
