摘要：

Under the frame work of Mie theory, a method has been developed to calculate the absorbance spectra of nanoparticles suspension containing a size distribution. The silver nanoparticles of two different sizes were first synthesized using a chemical reduction method and characterized by UV-Visible spectroscopy, dynamic light scattering, and transmission electron microscopy techniques. A model size-distribution were proposed and fitted to the experimental absorbance spectra using the described method. Better semiqualitative fitting to the experimental spectra were obtained by our proposed model in comparison to those obtained by single particle model.
