| 中文摘要 | monodisperse, well-defined, and photoluminescent cef(3), cef(3):tb(3+), and cef(3):tb(3+)@laf(3) core/shell nanocrystals (ncs) with small particle sizes (< 15 nm) have been successfully synthesized by a high-temperature thermolysis in high boiling solvent of oleic acid (oa) and 1-octadecene (ode). the morphology, phase, composition, and the fluorescent properties of the as-synthesized samples were well characterized by means of transmission electron microscopy (tem), high-resolution transmission electron microscopy (hrtem), x-ray diffraction (xrd), x-ray photoelectron spectra (xps), photoluminescence (pl) spectra, and kinetic decays, respectively. it is found that the as-synthesized ncs consist of monodisperse nanoparticles with narrow size distribution, which can easily disperse in nonpolar cyclohexane solvent to form transparent colloid solutions. the cef(3), cef(3):tb(3+) and cef(3):tb(3+)@laf(3) colloidal solutions show the characteristic emissions of ce(3+) 5d-4f (353 nm) and tb(3+) 5d(4) -> 7f(j) (j = 6-3) transitions, respectively. the growth of the laf(3) shell on the cef(3):tb(3+) core ncs not only results in an increase of the average size, but significantly enhances the emission intensity and lifetime of the cef(3):tb(3+)@laf(3) core/shell ncs with respect to those of cef(3):tb(3+) core ncs. moreover, a transparent and fluorescent ncs/polydimethylsiloxane (pdms) composite with regular dimension was also prepared by an in situ polymerization route. |
