英文摘要	emission-tunable mg2al4si5o18:eu2+, mn2+ and mg2al4si5o18:eu2+, tb3+ cordierite phosphors have been synthesized by a high-temperature solid-state reaction technique. photoluminescence and energy transfer in mg2al4si5o18:eu2+, mn2+ occur via a resonance-type dipole-quadrupole interaction mechanism, and the critical distance of the energy transfer is calculated to be 11.1 a. we found that the emission colors could be tuned from blue (0.19, 0.26) to white (0.41, 0.37) via the energy transfer of eu2+ -> mn2+ and from blue to green (0.28, 0.45) via the energy transfer of eu2+ -> tb3+. the green emission is realized in the mg2al4si5o18:eu2+, tb3+ phosphors on the basis of the highly efficient energy transfer from the eu2+ to tb3+ ions. finally, the color tunable emission with varied hues has been obtained in eu2+, tb3+, or mn2+ activated mg2al4si5o18 phosphors, making them potential emission-tunable phosphors for near-uv leds.
