Abstract
New optical medium consists of CdS nano particles (NPs) in a matrix of a low density polyethylene (LDP). It is shown, that the structure and optical properties of NPs depend on both concentration and NPs size in a matrix. For CdS NPs the average size of particles has made from 4,5 to 7 nanometers for concentration from 10 wt. % to 40 wt. % correspondingly. The optical reflectance and absorption spectra of nanocomposite materials were measured at room temperature in the visible and near-infrared regions. It is shown that, with an increase in the NPs concentration in the dielectric matrix the absorption coefficient rises mainly. Whereas an increase in the NPs size only for fixed concentration has effect on the set of optical medium parameters such as spectral position of absorption maximum and so on.
