在目前的手稿中，我们开发了一种方法，以确定所有的特征尺寸的CdSe种子CdS纳米棒仅通过他们的消光光谱，而不需要电子显微镜的研究。从吸收光谱的特征点可以推导出芯直径、总直径、总长度和摩尔消光系数。我们仔细研究了我们的假设在哪个尺寸范围内是有效的，并给出了预期误差的估计，使读者有可能决定这种方法对他们各自的系统是否足够准确。我们的方法显示了一种舒适和快速的方法来分析这些目前常用的纳米棒。
In the present manuscript we develop a method to determine all characteristic dimensions of CdSe seeded CdS nanorods solely via their extinction spectra without the need for electron microscopical investigations. In detail, the core diameter as well as the overall diameter and length and the molar extinction coefficient can all be derived from characteristic points in the absorption spectra. We carefully investigate in which size regime our assumptions are valid and give an estimation of the expected error, making it possible for the reader to decide whether this method is sufficiently accurate for their respective system. Our method displays a comfortable and fast route to analyze these nowadays often used nanorods.
