Abstract

ZnO crystal whiskers were prepared via a simple thermal evaporation of a mixture of ZnS and Fe(NO3)3. The growth process was carried out in an alumina tube at 1300°C using Ar mixed with 5% H2 as the carrier gas. The ZnO whiskers obtained had diameters ranging from 200 to 500 nm and lengths up to several hundreds of micrometers. The photoluminescence spectrum of as-grown ZnO whiskers was studied. The influences of reaction temperature, time, and carrier gases on the formation of the whiskers were investigated. A preliminary growth mechanism of the ZnO crystal whiskers was proposed. © 2001 Elsevier Science B.V.
