(YAGG) (x = 0, 0.02, 0.04, 006, 0.08, 0.10) phosphors were prepared by high temperature solid state reaction method. X-ray diffraction and fluorescence spectrum techniques were used to analyze the samples. The luminescence and energy transfer properties of samples were discussed in detail. The results indicated that a new emission peak located at 617 nm corresponding to the (4)G(5/2) -> H-6(5/2) transition of Sm3+ ion were observed after co-doping of Sm3+ ions. Energy transfer from Ce3+ to Sm3+ ions was demonstrated in YAGG host based on the emission spectra which lead to the decreases of emission intensity of Ce3+ ions with the increase of Sm3+ concentration. The energy transfer efficiency between Ce3+ and Sm3+ ions as high as 69.3% was calculated. The energy transfer type from Ce3+ to Sm3+ ions was supposed to be a resonant type through dipole-dipole.
