  • The Sr4Al14O25:M and doped Sr4Al14O25:M+Sm3+ (M=Mn4+, Cr3+) phosphors were syn-thesized by a solid-state reaction method and their luminescent properties were investi-gated. The results showed that the co-doping of Sm ions did not change the positions of excitation band and emission band but signi cantly improved the luminescent properties of Sr4Al14O25:Cr3+ phosphors; whereas, the emission intensity of Sr4Al14O25:Mn4+ was re-dueced remarkably when Sm ions were co-doped. In addtion, a radiative-form energy transfer from Sm3+ to Cr3+ was observed for the first time in the Cr, Sm co-doped Sr4Al14O25 phos-phors. The results indicated that Sm ions could signi cantly improve the emission intensity of Sr4Al14O25:Cr3+, making the Sm3+co-doped Sr4Al14O25:Cr3+ phosphor a promising can-didate for the applications in display and solid state lightening.
