中文摘要eu(3+), tb(3+), and dy(3+)-doped li(3)ba(2)y(3)(moo(4))(8) phosphors were prepared by the conventional solid-state reaction. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), photoluminescence (pl) spectra, and decay lifetimes were utilized to characterize the resulting samples. after annealed at 900 degrees c for 12 h in air, pure phase of the samples formed. under uv or blue light excitation at 395 nm (for eu(3+)), 488 nm (for tb(3+)) and 388 nm (for dy(3+)), the li(3)ba(2)y(3)(moo(4))(8):eu(3+), li(3)ba(2)y(3)(moo(4))(8):tb(3+), and li(3)ba(2)y(3)(moo(4))(8):dy(3+) phosphors exhibit the characteristic emissions of eu(3+)((5)d(0)-(7)f(2), red), tb(3+) ((5)d(4)-(7)f(5), green), and dy(3+) ((4)f(9/2)-(6)h(13/2), yellow) with a high color purity, respectively. the optimum doping concentrations and the corresponding pl quantum efficiencies for eu(3+), tb(3+), and dy(3+) ions in the li(3)ba(2)y(3-x)(moo(4))(8):xln(3+) (ln = eu, tb, dy) systems were determined to be x = 2.4, 2.4, 0.1 and 63%, 20%, 58%, respectively. the luminescence mechanism and concentration quenching effect were discussed in detail. these phosphors have potential applications in solid-state lighting technology for white led with suitable excitation of near-uv light or blue light.
