Optical properties of nanocomposite materials based on plasmon nanoparticles
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2018, Vol 21, Issue 2
Abstract
In this work, optical properties of nanocomposite materials based on plasmon metallic spherical nanoparticles have been studied. The authors have compared four different effective theories that take into account the size dispersion, interaction between nanoparticles and extrinsic size effect for calculation of the effective refractive index of Au, Ag and Cu nanoparticles in polymer. It has been demonstrated that size distribution induces an inhomogeneous broadening and change in the amplitude of plasmon band. The lowest shift of resonance characteristics has been observed for copper based nanocomposite for all the effective theories. It has been shown that the same nanocomposite material but with other parameters (size and concentration of inclusions) can be described by the different effective theories.
