摘要:

本文系统地比较了三种方式制备的ZnO纳米棒阵列的结构和性能的异同.根据水热法生长液中碱来源的不同,ZnO纳米棒阵列的生长方式分为三种:N方式(氨水)、H方式(六次甲基四胺)和NH方式(两次N方式和一次H方式).通过扫描电子显微镜,对这三种方式生长的ZnO纳米棒阵列形貌进行了表征.此外,利用X射线衍射仪、透射电子显微镜和激光拉曼光谱对ZnO的结晶性能进行比较.结果表明,ZnO纳米棒阵列的取向性N≈NH>H,ZnO的晶体质量H>NH>N.NH方式综合N方式和H方式的优势,得到了取向性和晶体质量优良的ZnO纳米棒阵列.这将为在进一步应用中有效地选择ZnO纳米棒阵列的制备方式提供重要信息.

Abstract:

In this work, we systematically compared the structure and crystalline quality of ZnO nanorod arrays which were prepared by three methods. According to the basic source of the hydrothermal growing solution, ZnO nanorod was prepared by using a) ammonia solution (N method), b) hexamethylene tetramine (H method) and c) alternating of 2N and H (NH method), respectively. The morphology and crystalline quality of the ZnO NW array have been characterized by using scanning electron microscopy, Raman spectroscopy, X-ray diffractometer and transmission electron microscopy. The results demonstrate that ZnO prepared with N and NH method has better orientation than that of H method, and an increasing crystalline quality trend of N
