Abstract

Reverse micelles have been used to make nanosized silver sulfide particles. The size distribution is evaluated from TEM micrographs and from fluorescence spectroscopy experiments. The luminescence spectrum, measured at 2 K, shows that the distribution is narrow but contains also particles with diameters too small for detection with TEM. By coating the particles with dodecanethiol, 2D and 3D self-assemblies composed of silver sulfide nanoparticles are observed. Monolayers organized in a hexagonal network in a very large domain are observed. Furthermore, 3D layers are highly ordered and form a face-centered cubic structure.
