Design parameters of nanocomposite matrices deposited on silicon substrates, in the optical domain

The purpose of the study is to optimize the design parameters of nanocomposites matrices deposited on silicon substrate, in the optical domain. Specifically, the interaction of polarized photons with several samples of nanocomposite matrices, consisting of different concentrations of gold nanoparticles dispersed into different concentrations of PVA (poly-vinyl alcohol), deposited on silicon substrates at different spin coating speeds, were studied. Backscattered photons, under co-polarized and cross-polarized transmitter-receiver geometries, were detected and the degree of linear polarization (DOLP) was estimated. The outcome of this study allow us to assess the optimal design parameters of nanocomposites in the optical domain. It is of paramount significance to determine how nanostructures can be effectively integrated into polymer matrices and what new information or enhanced optical properties can be achieved.
