Modeling electrical and optical spectral responses of homogeneous nanocomposites

• Describing the induced anisotropic electric field as tensor quantities inside a nanocomposite.
• Evaluating the effective electrical conduction and permittivity of a homogeneous nanocomposite.
• Modeling optical dispersion spectrum and UV–visible absorption spectrum of nanocomposites.
• Checking the model in silver nanocolloid.

In this study, electric field diffraction by a nanoparticle is studied using Legender series and extended for many particles in three dimensions. In the presence of an external dc electric field, the electric field induced by all the particles is added together based on the superposition principle and the electric field distribution would be obtained on an unlimited sheet inside the host matrix. Using this field distribution, pure displaced electric charge and passed current would be evaluated and the effective electrical conductivity and permittivity would be obtained. These parameters could predict the optical spectral responses of nano-composites such as the UV–visible absorption spectrum and refractive dispersion spectrum.

Electrical and optical properties of a nano-composite has been studied by the distribution of the electric field on an plane inside it, that is scattered by arrangement of particles.Figure optionsDownload as PowerPoint slide
