Abstract
A new borate compound NaSr4(BO3)3 doped with Ce3+, Mn2+ was prepared by a solid-state reaction at high temperature. The photoluminescence (PL) excitation and emission spectra, low temperature emission spectra and decay curves of Ce3+, Mn2+ in NaSr4(BO3)3 were studied. The PL properties of Ce3+, Mn2+ co-doped NaSr4(BO3)3 were also investigated. NaSr4(BO3)3:Ce3+,Mn2+ phosphors emit two distinctive colors: a blue band centered at 435 nm originating from Ce3+ and a red band at 660 nm caused by Mn2+. The results indicate that there exist energy transfer from Ce3+ to Mn2+ in the NaSr4(BO3)3 doped with Ce3+, Mn2+ system.
