| 英文摘要 | Core-shell cds nanocrystals, which were modified by different-chain length alkyl thiols, were chemically synthesized by a new liquid-liquid two-phase method. the structure and composition were investigated with uv-vis absorption spectra, x-ray diffraction, and transmission electron microscopy. the results showed these as-prepared samples consisting of a nano-cds core and a capped-layer of thiols chemically absorbed on the surfaces and the modifiers had a great effect on the size and optical property of the inorganic nano-core. according to further analysis, it was found that the size of cds nano-core had a quasiparabola relation with the chain length of the modifiers, which was caused by the competitive result of the surface mobility and self-assembly order of the modifiers in the course of nucleation and growth of cds nano-core. |
