Heat treatment for the hierarchical ZnO column arrays
首发时间:2010-05-06
Abstract:In order to investigate the effect of heat treatment on the structural and optical properties of hierarchical ZnO column arrays, the as-grown hierarchical ZnO column arrays were annealed in air from 200 to 650 oC. The UV-vis spectra showed changes of the structure with different annealing temperatures. Photoluminescence intensity of annealed samples was increased at about 520 nm. In addition, the mechanism of visible emission was discussed.
