| Summary: | In this work, we reported the synthesis of cadmium selenide-gold (CdSe-Au) hybrid nanorods. The growth substrates, CdSe nanorods, were synthesized using a simple mono-injection method. The growth models for CdSe with different morphologies were proposed, and validated by the experimental results. It can be briefly described as concentrated CdSe monomers were prone to forming isotropic CdSe nanoparticles; while diluted CdSe monomers were prone to forming anisotropic CdSe nanorods. The growth of Au nanoparticles on the surface of CdSe nanorods was achieved via galvanic replacement reactions between Au ions (AuCl3) and CdSe nanorods at room temperature. By adjusting the reaction times, the sizes of Au nanoparticles could be tuned from 1.7 ± 0.6 nm to 2.4 ± 0.9 nm. |
