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+.
