چکیده:

Silver nanoparticles coated with a uniform, thin shell of tin dioxide were synthesized via a remarkably simple route, where the reduction of Ag+ to Ag0 and the deposition of SnO2 on the surface of silver crystallites took place stepwise. The prepared dispersions of coated nanoparticles displayed a surface plasmon band, which was red-shifted with respect to that of bare Ag. TEM images confirmed the formation of core-shell structure. Introduction of these composite nanoparticles into PVA matrix resulted in a polymeric nanocomposite, thin films ofwhich were investigated structurally by TEM and STM
