摘要：

Eu2+ and Mn2+ co-doped SrMg2(PO4)(2) phosphors with blue and red two emission bands were prepared by the high temperature solid state method and their luminescent properties have been investigated as a function of activator and co-activator concentrations. Resonance-type energy transfers from Eu2+ to Mn2+ were discovered by directly overlapping the Eu2+ emission spectrum and the excitation spectrum of Mn2+. Efficiencies of energy transfer were also calculated according to the changes of relative intensities of Eu2+ and Mn2+ emission. According to the principle of energy transfer, we demonstrated that the phosphor SrMg2(PO4)(2):Eu2+, Mn2+ with double emission bands exhibited a great potential as a phosphor for ultraviolet light-emitting diodes and the relative intensities of blue and red emission could be tuned by adjusting the contents of Eu2+ and Mn2+.
