| 英文摘要 | R2moo6:eu3+ (r = gd, y, la) phosphors were prepared by the pechini sol-gel process. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), reflectance spectra, photoluminescence (pl) spectra, and lifetimes were used to characterize the resulting phosphors. the results of xrd indicate that all of the r1.96eu0.04moo6 (r = gd, y, la) phosphors crystallized completely at 800 degrees c. y1.96eu0.04moo6 and gd1.96eu0.04moo6 are of isomorphous monoclinic (alpha) structure, while la1.96eu0.04moo6 preferentially adopts the tetragonal (gamma) form. fe-sem study reveals that the samples mainly consist of aggregated particles with an average grain size ranging from 100 to 250 nm. the luminescent properties of r2moo6:eu3+ (r = gd, y, la) phosphors are largely dependent on their structure, grain size, and powder morphology. the isomorphous y2moo6:eu3+ and gd2moo6:eu3+ phosphors show very similar luminescence properties, which differ greatly from that of the la2moo6:eu3+ phosphor. |
