| 中文摘要 | magnetic luminescent nanocomposites were prepared via a layer-by-layer (lbl) assembly approach. the fe3o4 magnetic nanoparticles of 8.5 nm were used as a template for the deposition of the cdte quantum dots (qds)/polyelectrolyte (pe) multilayers. the number of polyelectrolyte multilayers separating the nanoparticle layers and the number of qds/ polyelectrolyte deposition cycles were varied to obtain two kinds of magnetic luminescent nanocomposites, fe3o4/pen/cdte and fe3o4/(pe3/cdte)(n), respectively. the assembly processes were monitored through microelectrophoresis and uv-vis spectra. the topography and the size of the nanocomposites were studied by transmission electron microscopy. the lbl technique for fabricating magnetic luminescent nanocomposites has some advantages to tune their properties. it was found that the selection of a certain number of the inserted polyelectrolyte interlayers and the cdte qds loading on the nanocomposites could optimize the photoluminescence properties of the nanocomposites. furthermore, the nanocomposites could be easily separated and collected in an external magnetic field. |
