| 英文摘要 | Eu2+/tb3+ doped sr2si5n8 phosphors were prepared by carbothermal reduction and nitridation method. the luminescence of tb3+/eu2+ co-doped sr2si5n8 were investigated. the experimental results indicated that owing to spin-allowed f -> d transition rule the four emission lines located at 490, 543, 585, and 623 nm which ascribed to the d-5(4)-> f-7(j) (j = 6, 5, 4, 3) transitions were observed under 330 nm excitation. no obvious changes in spectral line shape were observed for sr2si5n8:eu2+ co-doped with tb3+. however, the emission intensity was improved by about 20% with tb3+ doping concentration of x = 0.01 mainly because of the electric multipole energy transfer from tb3+ to eu2+. |
