Effect of the Titanium Dioxide Shell on the Plasmon Properties of Silver Nanoparticles

Abstract

The results of the synthesis of Ag - TiO₂ nanostructures were presented. The optical properties of silver nanoparticles and Ag - TiO₂ structures were studied. The size and shape of Ag - TiO₂ nanostructures were determined. The electron density in silver, the damping constant of plasma oscillations, and the ratio between the masses of the Ag core and the TiO₂ shell were determined from the absorption spectra of Ag and Ag - TiO₂ solutions. It was shown that the semiconductor shell of titanium dioxide leads to a decrease in the electron density in silver nanoparticles and the damping constant of plasma oscillations.
