SERS and CARS studies on composite materials based on single-walled carbon nanotubes functionalized with conjugated macromolecular compounds


Project Director: Dr. Mihaela Baibarac

Theme code: 04-4-1133-2018/2020

Year: 2019

Laboratory in JINR: Frank Laboratory of Neutron Physics – FLNP

Partners in Romania: National Institute of Materials Physics – NIMP

Responsible persons: Dr. Mihaela Baibarac (NIMP), Prof. Dr. Grigory Arzumanyan (FLNP)

The overall objective of this project is the understanding of the enhancement processes in the Surface Enhanced Raman Scattering (SERS) and coherent anti-Stokes Raman scattering (CARS) geometries using composite materials based on highly separated semiconducting and metallic single-walled carbon nanotubes functionalized with conjugated macromolecular compounds, investigated with the two complementary infrastructures from NIMP and FLNP.

The specific objectives of this project:

  1. The enhancement mechanism in the SERS spectroscopy in the particular case of the poly(3-hexyl thiophene) (P3-HTh)/single-walled carbon nanotubes (SWNTs) composites, prepared by electrochemical and chemical ways;
  2. The coherent anti-Stokes Raman scattering mechanism in the case of the P3-HTh/SWNTs composites deposited on the rough metallic supports.
