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 dipoledipole 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 4.510-36 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 Ce 3  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  Sm 3Eu3 transfer occurs from 4G5/2 of Sm3 to 5D0 of Eu3. The rate constant of 8.510-40 cm6 s-1 and the critical transfer distance of 0.89 nm are evaluated. 2010 Elsevier B.V.

Cr3+ activated red (694 nm) long persistent phosphorescence originating from 2E-4A2 transition is observed in 4SrO·7Al2O3: Cr3+  Eu2+  Dy3+ system. It is demonstrated that the red phosphorescence is resulted from the conversion of Eu2+ activated blue phosphorescence through persistence energy transfer from Eu2+ to Cr3+. The excitation spectra of the 694 nm emission exhibit strong f-d band of Eu 2+  indicating the existence of the energy transfer. The dependence of lifetimes and intensities of the red and blue emissions on Cr3+ concentrations are studied. The intensity ratio of the red to blue emission bands obtained from photoluminescence spectra is in good agreement with that obtained from fluorescence lifetime measurements. The decay curves of the red phosphorescence at 694nm are also studied.
