| 总结: | Efficient far-field coupling of longitudinal plasmon modes of gold nanorods makes them prospective for optical imaging. A facile one-step hydrothermal synthesis of stabilized gold nanorods in an aqueous solution at 85 °C is reported. High aspect ratio of these nanorods ranging from 10 to 57 is achieved using methyltrioctylammonium chloride (TOMAC) as a phase transfer reagent. The growth of {100} and {110} facets being more favorable to conception is facilitated via the capping agent (TOMAC). These highly elongated nanorods reveal visible luminescence at around 410 nm, which is attributed to the ligand-metal charge transition mechanism. We affirm that such plasmonic nanorods acquiring superior nonlinear optical properties can be used as a vehicle for single-particle measurements. |
