中文摘要pure ca2ba3(po4)(3)cl and rare earth ion (eu2+/ce3+/dy3+/tb3+) doped ca2ba3(po4)(3)cl phosphors with the apatite structure have been prepared via a pechini-type sol gel process. x-ray diffraction (xrd) and structure refinement, photoluminescence (pl) spectra, cathodoluminescence (cl) spectra, absolute quantum yield, as well as lifetimes were utilized to characterize samples. under uv light excitation, the undoped ca2ba3(po4)(3)cl sample shows broad band photoluminescence centered near 480 nm after being reduced due to the defect structure. eu2+ and ce3+ ion doped ca2ba3(po4)(3)cl samples also show broad 5d -> 4f transitions with cyan and blue colors and higher quantum yields (72% for ca2ba3(po4)(3)cl:0.04eu(2+); 67% for ca2ba3(po4)(3)cl:0.016ce(3+)) for dy3+ and tb3+ doped ca2ba3(po4)(3)cl samples, they give strong line emissions coming from 41 4f transitions. moreover, the ce3+ ion can transfer its energy to the tb3+ ion in the ca2ba3(po4)(3)cl host, and the energy transfer mechanism has been demonstrated to be a resonant type, via a dipole-quadrupole interaction. however, under the low voltage electron beam excitation, tb3+ ion doped ca2ba3(po4)(3)cl samples present different luminescence properties compared with their pl spectra, which is ascribed to the different excitation mechanism. on the basis of the good pl and cl properties of the ca2ba3(po4)(3)cl:a (a = ce3+/eu2+/tb3+/dy3+), ca2ba3(po4)(3)cl might be promising for application in solid state lighting and field-emission displays.
