中文摘要	nacapo4:ce3+,tb3+ phosphors were prepared by a solid-state reaction. their luminescence properties reveal that an efficient energy transfer from the ce3+ to tb3+ ions occurs, and its mechanism is a resonant type by means of a dipole-quadrupole reaction. the critical distance of the energy transfer has been calculated by concentration-quenching and spectral-overlap methods. the varied emitted color of the phosphors from blue to yellow-greenish can be achieved by properly tuning the relative ratio of ce3+ and tb3+ through the energy transfer from the ce3+ to tb3+ ions. these results indicate that nacapo4:ce3+,tb3+ is potentially useful as a highly efficient, green-emitting, uv-convertible phosphor for white-light-emitting diodes. moreover, the accurate oscillator strength ratio of the electric quadrupole-to-dipole transitions for the tb3+ ion was obtained to be about 10(-3), which may be of much significance in the estimate of the critical distance of the dipole-quadrupole interaction between ce3+ and tb3+ ions through dexter's energy-transfer theory.
