| 中文摘要 | in this paper, the color point tuning of y3al5o12 : ce3+ phosphor has been realized by the incorporation of mn2+-si4+. the mn2+ ions occupy the dodecahedral crystallographic y3+ site, while the si4+ ions substitute the tetrahedral al3+ crystallographic site in the obtained powder. under 450 nm excitation, the yag : ce3+, mn2+, si4+ samples exhibit the typical yellowish-green emission band of the ce3+ ions, as well as an orange emission band of the mn2+ ions. furthermore, the intensity ratio of the orange/yellowish-green band can be enhanced through the increase of mn2+-si4+ content. the intense orange emission band of the mn2+ ions is attributed to the effective energy transfer from the ce3+ to mn2+ ions, which has been justified through the luminescence spectra and the fluorescence decay dynamics. the related mechanism was demonstrated to be the electric dipole-quadrupole interaction based on the inokuti-hirayama theoretical model, and critical distance is calculated to be 8.6 angstrom by the spectral overlap method. |
