Laser co-photolytic approach to copper(I) bromide/polymer nanosol and nanocomposite

KrF laser co-photolysis of Cu(II) acetylacetonate and 1-bromoeicosane in 2-propanol results in the formation of CuBr/polymer colloidal solution aging of which results in sedimentation of CuBr/polymer nanocomposite. This clean process involves a reaction between two photo-products (nano-sized Cu and a brominating reagent) and photolytic formation of polymer. The CuBr nanoparticles embedded in a photo-produced polymer possess zinc blende-type cubic structure. The co-photolytic procedure represents a new approach to polymer-stabilized nano-inorganic compounds.
