英文摘要	A series of single-doped ca9y(po4)(5)(sio4)f1.5o0.25:ln(3+) (ln(3+) = eu3+/tb3+/dy3+/sm3+) phosphors have been prepared via conventional high-temperature solid-state reaction. the structural refinement, photoluminescence properties, and decay curves were studied in detail. under near-uv excitation, the ca9y(po4)(5)(sio4)f1.5o0.25:eu3+/tb3+/dy3+/sm3+ phosphors show the characteristic emissions of eu3+ (d-5(0)-f-7(2), red), tb3+ (d-5(4)-f-7(5), green), sm3+ ((4)g(5/2)-h-6(7/2), red), and dy3+ (f-4(9/2)-h-6(13/2), yellow). the emission intensities of ca9y(1-x/z)(po4)(5)(sio4)f1.5o0.25:xeu(3+)/zsm(3+) are maximized when x = 0.16 and z = 0.10, and the concentration quenching mechanisms are both dominated by dipole-dipole interactions. the excitation spectra of the ca9y(po4)(5)(sio4)f1.5o0.25:eu3+/sm3+ phosphors show the strongest absorption at about 400 nm, which matches well with the commercially available near-uv-emitting ingan-based light emitting-diode (led) chip. finally, a red led was fabricated using the present phosphors (with the composition of ca9y(po4)(5)(sio4)f1.5o0.25:eu3+/sm3+) and exhibited a red emission with high color purity. all the results indicate that ca9y(po4)(5)(sio4)f1.5o0.25:ln(3+) phosphors are promising phosphors for white leds.
