Abstract:

Synthesis works on Ag clusters in ordered phase of O/W, W/O and LC are reported. Stabilized Ag particles and gel can be synthesized from high concentration of AgNO3 reduced by N2H4•H2O applying W/O/W or LC. The gel and particles were characterized by UV-visible spectrum, X-ray diffraction and transparent electron microscopy. We found the layer structure surrounding Ag clusters which illustrateds the double layer ordered phase coatings of surfactant and auxosurfactant.

Key words: Dissolvable, Ag cluster, W/O/W, LC
