中文摘要	cef3, cef3:tb3+, and cef3:tb3+/laf3 (core/shell) nanoparticles were prepared by the polyol method and characterized by x-ray diffraction (xrd), transmission electron microscopy (tem), x-ray photoelectron spectra (xps), uv-vis absorption spectra, photoluminescence (pl) spectra, and lifetimes. the results of xrd indicate that the obtained cef3, cef3:tb3+, and cef3:tb3+/laf3 (core/shell) nanoparticles crystallized well at 200 degrees c in diethylene glycol (deg) with a hexagonal structure. the tem images illustrate that the cef3 and cef3:tb3+ nanoparticles are spherical with a mean diameter of 7 nm. the growth of the laf3 shell around the cef3:tb3+ core nanoparticles resulted in an increase of the average size (11 nm) of the nanopaticles as well as in a broadening of their size distribution. these nanocrystals can be well-dispersed in ethanol to form clear colloidal solutions. the colloidal solutions of cef3 and cef3:tb3+ show the characteristic emission of ce3+ 5d-4f (320 nm) and tb3+ d-5(4)-f-7(j) (j = 6-3, with d-5(4)-f-7(5) green emission at 542 nm as the strongest one) transitions, respectively. the emission intensity and lifetime of the cef3:tb3+/laf3 (core/shell) nanoparticles increased with respect to those of cef3:tb3+ core particles.
