Soft-solution route to various ZnO nanoplate arrays

Abstract

Three different ZnO nanoplate arrays on Si-wafer were successfully synthesized at 95 °C from ZnO nanoparticles with modified surface by citrate anion. Shape, size, density, and orientation of the resulting nanoplates were dramatically changed by the nucleus seed concentration, which was controlled through different coating processes on the substrate. © 2010 The Royal Society of Chemistry.
