Abstract
Dodacanethiol-capped silver "quantum dot"particles (Q-particles) have been synthesized using a novel biphasic microemulsion (Winsor II type) of diethyl ether/AOT/water. FT-IR investigations and elemental analyses support the encapsulation of silver particles by dodecanethiol while the transmission electron micrograph reveals an average size of 11 nm. The optical band corresponding to a surface plasmon of silver confirms the nanoparticle nature. The evidence from X-ray photoelectron spectroscopy investigation confirms the metallic state of silver (Ag0) and the encapsulation by thiol molecules. The thermogravimetric and differential thermal analysis indicates a heterogeneous interaction between thiol group and silver surfaces.
