摘要	The Ce3+-activated, Tb3+ activated, and Ce3+ and Tb3+ co-activated phosphors 2SrO-nB(2)O(3)-(1-n)P2O5 were synthesized by the solid-state reaction. The structures, photoluminescent spectra and dynamics of them were systemically studied. The results demonstrate that the structure of the samples with n = 0.10-0.50 belongs to the hexagonal phase. When n is beyond this range, the structures are the mixed phases of alpha-Sr2P2O7 and Sr2B2O5. The optimum composition is determined to be n = 0.25 for the 2SrO-nB(2)O(3)-(1-n)P2O5 phosphors. As n varies from 0.01 to 0.50, the lifetime of Ce3+ ion increases gradually, while the lifetime of Tb3+ ion decreases, indicating that the energy transfer efficiency decreases with the increase of n. The ET efficiency between Ce3+ and Tb3+ in the optimum composition reaches to 70%. The present results demonstrate that the Ce3+ and Tb3+ co-activated hexagonal 2SrO-0.25B(2)O(3)-0.75P(2)O(5) powders can possibly be applied as the newly developed green efficient phosphors in the field of lighting and display.
