摘要

This paper demonstrates three cases of simple analytical classical Maxwell-Garnett model to estimate the size and concentration of silver and gold nanoparticles and their interface. The examples show that the model can satisfactorily interpret the spectral properties of ISTC and, in particular, to determine the presence and thickness of the shell on the surface of metallic nanoparticles in colloidal solution, and their interface in porous glass and complex colloidal solutions. The results can be used to study the optical properties of heterogeneous systems with metal nanoparticles, including the evolution of biological systems in vivo and the type of interaction precious metal nanoparticles with biological objects.
