WitrynaStandard aspect ratios (length divided by width) are 3-5. Nanorods are produced by direct chemical synthesis. A combination of ligands act as shape control agents and bond to different facets of the nanorod with different strengths. This allows different faces of the nanorod to grow at different rates, producing an elongated object. WitrynaHere we show this experimentally and in fact, according to our results, at diameters >50nm, the SPR max is dependent more on the diameter than on the length. Figures and Tables 1-4 show the resultant plots of Aspect Ratio vs. SPR for diameters 10nm, 25nm, 40nm, and 50nm respectively.
