Anglies nanodarinių su sidabru paruošimas ir charakterizavimas

Anotacija

The creation of nanocomposite materials based on fullerene and a rare metal with unique hybrid properties is promising for use in chemical sensors, photocatalytic devices and energy storage devices. A nanocomposite thin film containing fullerene C₆₀ and silver (Ag) nanoparticles was synthesized by introducing an Ag nanoparticle into the fullerene matrix using thermal evaporation of the solution. The morphological and optical properties of both solutions consisting of fullerene and silver and the C₆₀–Ag nanocomposite at different concentrations of the components were studied using optical absorption, refractometry, dynamic light scattering, Raman spectroscopy and electron microscopy. The surface plasmon resonance (SPR) band of the C₆₀–Ag nanocomposite under different conditions was determined. A significant redshift (∼12 nm) of the SPR band was observed with annealing a thin film at 60°C.
