Abstract

The morphology of gold nanoparticles was controlled with hydrogentetrachloroaurate (HAuCl ₄) and polyvinylpyrrolidon (PVP) through a polyol process using ethyleneglycol as solvent and reducing agent. The polyol process gave various particle morphologies: trihedron, tetrahedron, hexahedron, and sphere in the size range of 100-1000 nm. The polyhedral nanoplate fraction (PNF) was increased by injection of HAuCl ₄ and PVP to preheated ethyleneglycol. The synthesis method, so-called rapid heating process, provided a suitable crystal growth condition for formation of nanoplates because of rapid reduction of HAuCl ₄ to form gold nuclei and their oriented crystal growth under the affection of PVP at high temperature. The rapid heating process was found to straightforwardly obtain polyhedral gold nanoplates with an extremely small fraction of spherical particles. Particularly, trihedral gold nanoplates were obtained selectively in a short reaction time.
