Laser-induced synthesis of metal-carbon materials for implementing surface-enhanced Raman scattering

摘要

Metal-carbon materials exhibiting surface-enhanced Raman scattering have been synthesized by laser irradiation of colloidal systems consisting of carbon and noble metal nanoparticles. The dependence of the Raman scattering intensity on the material composition and laser irradiation conditions has been investigated. The possibility of recording the Raman spectrum of organic dye rhodamine 6G, deposited in amount of 10(-6) M on the substrate obtained from a colloidal solution is demonstrated.
