Abstract

In this paper we present the experimental results and analysis of amorphous silicon nanoparticles (a-n-Si) optical properties. The optical properties of individual particles of a-n-Si imbedded in glycerol, water and conglomeration of particles have been studied. The optical absorption spectra for each nanocomposites measured in the spectral range from 300 to 1100nm differs much one from another, because it depends on the surrounding media, mainly, but not on the particles microstructure. This character of optical absorption in the visible range is defined by the double charge layer near the surface inside of the particles. The mechanism of the optical absorption is the composition of absorption by the surface electrons plasma waves and valence electron in strong static electric field created by double charge layer.
