The obtained ZnO nanostructure was characterized by XRD and SEM. The results of characterization indicate that the nanorods are high-quality single crystals growing along (001) direction with a high consistent orientation perpendicular to the substrate. SEM images show that the nanorods have a very narrow size distribution of 20-50 nm with the average diameter about 40 nm. The room temperature photoluminescence of the as-prepared ZnO films exhibits a strong UV emission at about 390 nm and a weak emission at about 460 nm. The ease of fabricating high-quality ZnO nanorod arrays in large scales will greatly promote the fundamental research and practical applications of the ordered one-dimention ZnO structure in various fields of nanoscale science and technology.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000189187400038&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)1302345-3472
