SELF-ORGANIZATION INTO 2D AND 3D SUPERLATTICES OF NANOSIZED PARTICLESDIFFERING BY THEIR SIZE

Self-assembly of silver sulfide, Ag2S, nanoparticles is reported for d ifferent particles sizes. Monolayers of particles organized in a hexag onal network an formed over very large domains, Snail or large aggrega tes can also be produced. The observations indicate that the formation of self-assemblies of nanoparticles strongly depends on the preparati on conditions of the samples, It is also shown that in the aggregates the particles are highly organized and form pseudocrystals with a face -centered cubic structure for various particles sizes.
