Charge storage and release onto Au and Ag nanoparticles in aqueous medium as probed by optical spectroscopy

Tunc, I.; Sezen, H.; Guvenc, H. O.; Süzer, Şefik (Cognizure, 2014)

Gold and silver nanoparticles in aqueous solutions can store negative or positive charges when, respectively, NaBH4, KI are introduced into the same media. The charge storage can be followed by the spectral shifts in the ...
Optical response of Ag-Au bimetallic nanoparticles to electron storage in aqueous medium

Tunc, I.; Guvenc, H. O.; Sezen, H.; Süzer, Şefik; Correa-Duarte, M. A.; Liz-Marzán, L. M. (2008)

Composition and structure dependence of the shift in the position of the surface plasmon resonance band upon introduction of NaBH 4 to aqueous solutions of gold and silver nanoparticles are presented. Silver and gold ...
