Zinc Powder Evaporation: an Efficient Way of Synthesizing a Wide Range of High-quality ZnO Nanostructures at Lower Temperature

摘要

We developed an efficient method in achieving a wide range of high-quality ZnO nanostructures by zinc powder evaporation at lower temperature. The synthesis"mjder specific conditions of ZnO nanostructures, such as comb-like structures, well-aligned nanorods, nanonails and core-shell ZnO/SiOx nanowires, were introduced in detailed respectively in this letter. Meanwhile, SEM, TEM, HRTEM and EDX investigations were performed on the products and revealed the crystal structure and the growth mechanism. These high-quality nanostructures enriched the family of ZnO nanomaterials and may have potential applications in optoelectronics, sensors and nanoscale mechanics research.
