摘　　要：以锌片为衬底,用硝酸锌和氨水为原材料,在90℃时由水热法合成了有序生长的ZnO纳米棒阵列。纳米棒长度为500~800 nm,直径约为100 nm,SEM图片显示该纳米棒顶部截面是六边形。XRD谱表明,ZnO纳米棒为六方纤锌矿结构。考察了制备温度、时间和物料比对合成的材料形貌和结构的影响。Well-aligned ZnO nanorod arrays were obtained at 90 ℃,using zinc foil as the substrate and zinc nitrate and ammonia as source materials,in the absence of any surfactants by hydrothermal method.As-synthesized ZnO nanorod arrays are from 500 to 800 nm in the length,and are about 100 nm in the diameter.The results show that the top of the nanorod is hexagonal and owns the wurtzite structure.Also,the effect of experimental parameters on the morphology and structure of as-products are studied systematically.
