The spectra of small gold nanoparticles (GNPs) were theoretically described following the modified Mie equations and by adopting the Kriebig-Drude model. The experimental dependence of the absorption maximal intensity of small spherical GNPs versus their diameter was compared with a theoretically derived relation. The theoretical description is validated by simultaneously obtained data from UV-Vis plasmon absorption spectra together with the size of GNPs measured by means of atomic force microscopy (AFM).

小金纳米粒子的等离子光谱从其大小的依赖性：原子力显微镜实验方法

理论上，按照改进的Mie方程并采用Kriebig-Drude模型描述了小金纳米颗粒（GNP）的光谱。将小球形GNP的最大吸收强度与其直径的实验相关性与理论推导的关系进行了比较。通过同时获得来自UV-Vis等离子体激元吸收光谱的数据以及通过原子力显微镜（AFM）测量的GNP尺寸，验证了理论描述。
