In this paper, the color point tuning of Y 3 Al 5 O 12 : Ce 3+ phosphor has been realized by the incorporation of Mn 2+ -Si 4+ . The Mn 2+ ions occupy the dodecahedral crystallographic Y 3+ site, while the Si 4+ ions substitute the tetrahedral Al 3+ crystallographic site in the obtained powder. Under 450 nm excitation, the YAG : Ce 3+ ,Mn 2+ ,Si 4+ samples exhibit the typical yellowish-green emission band of the Ce 3+ ions, as well as an orange emission band of the Mn 2+ ions. Furthermore, the intensity ratio of the orange/yellowish-green band can be enhanced through the increase of Mn 2+ -Si 4+ content. The intense orange emission band of the Mn 2+ ions is attributed to the effective energy transfer from the Ce 3+ to Mn 2+ 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 8.6A by the spectral overlap method.
