High-yield synthesis of large single-crystalline gold nanoplates through a polyamine process.
A polyamine process has been demonstrated for the high-yield preparation of single-crystalline gold nanoplates with several 10 microm in size, carried out by heating a concentrated aqueous solution of linear polyethylenimine and HAuCl4 at 100 degrees C. It suggests that the concentration of reactants is crucial to the formation of nanoplates.
