| Description | Hybrid nanocomposites consisting of a photosensitive polymer with dispersed metal nanoparticles attract considerable research interest in contemporary science and technology, because of their potential applications in photovoltaics, different kinds of molecular electronic devices, surface-enhanced spectroscopy and many other fields. Metal nanoparticles in an organic matrix show the surface plasmon resonance effect (i.e. collective oscillations of their free electrons resonating with incident radiation). Local increase of the optical field together with the energy and charge transfer can enhance efficiency of the coupled active organic structures. The proposed topic is focused on a solution of the local interaction between the metal nanoparticle and the polymer matrix. Theoretical modeling will be performed using both classical and quantum mechanical methods. The objective of the research is elucidation of the energy transfer and charge separation processes after photoexcitation in the studied nanocomposites and correlate it with the experimental data obtained from the optical and electrical measurements. Expected skills of the applicant correspond to the master degree level in physics. Advantage is the knowledge of the basics of the quantum chemistry. |
