摘要	Sr(3)Al(10)SiO(20)-SrAl(12)O(19), doped with Eu(2+), Cr(3+) and (Eu(2+) + Cr(3+)) is prepared by solid-state reaction and energy transfer from Eu(2+) to Cr(3+) in the phase of Sr(3)Al(10)SiO(20) is the focus of investigation. The spectrum of Sr(3)Al(10)SiO(20)-SrAl(12)O(19) : Eu(2+) shows f-d emission bands at 460 and 400 nm. Cr(3+) doped Sr(3)Al(10)SiO(20)-SrAl(12)O(19) yields emission lines at 688 and 696 nm and a broad emission band between 650 and 750 nm. The photoluminescence study and fluorescence lifetime measurements demonstrate efficient energy transfer from Eu(2+) to Cr(3+) in Sr(3)Al(10)SiO(20) : Eu(2+), Cr(3+). The emission lines peak at 688 nm and 696 nm, which, respectively, originate from (2)E-(4)A(2) transitions in the phases of SrAl(12)O(19) and Sr(3)Al(10)SiO(20). The broad emission band of Cr(3+) between 650 and 750 nm in the phase of Sr(3)Al(10)SiO(20) is considered to be the (4)T(2)-(4)A(2) transition by calculating the strength of the octahedral crystal field Dq, the Racah parameters B and C as well as by constructing the Tanabe-Sugano diagram.
