Rapid Hydrothermal Growth of ZnO Nanorods on a Magnetron Sputtered Thick ZnO Seed Layer

Abstract

In this work, we report rapid hydrothermal growth of ZnO nanorods on a magnetron sputtered thick ZnO seed layer. The ZnO seed layer on the glass substrarte is monocrystalline and formed by 600 °C annealing for 1 hour after magnetic sputtering. The morphology of the ZnO grain in the ZnO seed layer plays a critical role in the growing of the ZnO nanorods, and the slant ZnO grain results in the slant ZnO nanorod and connected ZnO nonrods. It is found that the average growth of the ZnO nanorods is ~75 nm/minute. The rapid grow rate may be owing to the monocrystallie and the pure water solution of the growth solution.

Cu-ZnO Nanostructures Synthesis and Characterization

“…FE-SEM microscopy showed an obvious temperature impact on the growth and morphology of the Cu-ZnO nanostructures. This is consistent with our previous work and that of others [28][29][30][31]. We believe that the growth and, hence, the change of particle size and shape, should be expected as temperature or incubation time, or maybe both, are increased.…”
