Abstract

Abstract:

The mechanism of the formation of ZnO nanoparticle by mixing zinc acetate and sodium hydroxide in ethanol solution was studied. It has been found that there are two pathways to obtain ZnO nanoparticle: one is a fast process which is characterized by the direct dehydration of Zn(OH)2 when Zn2+ is in excess; another is a slow process which is featured by the formation of [Zn(OH)4]2- complex and the subsequent nucleation of ZnO particle when OH- is in excess.

Key words: Zinc oxide, Nanoparticle, Semiconductor
