Specific Features of the Preparation of AgI Nanocrystals in Reverse Micelles of Aerosol OT

摘要: It was shown that the interrelation between mean size of AgI nanocrystals prepared in water pools reverse micelles as a result reaction KI and AgNO3 pool diameter has complex pattern is determined mainly by stability micellar system. Microemulsions with small (the up to 2 nm) are stable due presence micelle oligomeric phase, regardless effect structurization pools. In microemulsions diameters from 6 nm, such an phase absent leads avalanche-like growth their aggregation organic phase. As increases above stabilized because limited dimensions structured layer deceleration intermicellar exchange. When excess amount added microemulsion, screening shell ions formed around nanocrystals, thus complicating formation icelike structure
