摘要	Non-radiative energy transfers (ET) from Ce3+ to Pr3+ in Y3Al5O12:Ce3+, Pr3+ and from Sm3+ to Eu3+ in CaMoO4:Sm3+, Eu3+ are studied based on photoluminescence spectroscopy and fluorescence decay patterns. The result indicates an electric dipole-dipole interaction that governs ET in the LED phosphors. For Ce3+ concentration of 0.01 in YAG:Ce3+, Pr3+, the rate constant and critical distance are evaluated to be 4.5 x 10(-36) cm(6) s(-1) and 0.81 nm, respectively. An increase in the red emission line of Pr3+ relative to the yellow emission band of Ce3+, on increasing Ce3+ concentration is observed. This behavior is attributed to the increase of spectral overlap integrals between Ce3+ emission and Pr3+ excitation due to the fact that the yellow band shifts to the red spectral side with increasing Ce3+. concentration. In CaMoO4:Sm3+, Eu3+, Sm3+-Eu3+ transfer occurs from (4)G(5/2) of Sm3+ to D-5(0) of Eu3+. The rate constant of 8.5 x 10(-40) cm(6) s(-1) and the critical transfer distance of 0.89 nm are evaluated.
