Abstract
Diagnostic of nanocomposite films formed by gold nanoparticles embedded in a polytetrafluorethylene matrix has been performed utilizing modulation polarization spectroscopy technique. The dependencies of annealing influence on morphology structure and LSPR parameters of Au-PTFE films were studied and discussed. Effective optical parameters of Au-PTFE films were obtained. Two types of LSPR were detected: the first is on isolated non-interacting Au NPs and the second – between Au NPs caused by dipole fields’ interactions. The experimental data were confirmed by theoretical calculations. Radiative and non-radiative modes of surface plasmons were studied. Plasma frequencies were obtained for Au-PTFE films with unheated structure and annealed at temperatures of 300 and 520 °C by measuring of spectral characteristics of the angle of isotropic reflection θp=0(λ).
