摘　　要：采用种子生长法,通过调整生长溶液中Cu(NO_(3))_(2)的浓度制备金(Au)纳米棒,并通过扫描电子显微镜(SEM)和紫外吸收光谱图对样品进行表征。SEM结果显示Cu(NO_(3))_(2)的加入使Au纳米棒有棒状物和块状物两种,随着Cu(NO_(3))_(2)用量的增加,棒状物的数量减少而块状物数量增加。当Cu(NO_(3))_(2)用量为3.0μL时,棒状物最少,结合紫外吸收光谱图发现样品的吸收峰只有一个,不存在Au纳米棒的纵向特征吸收峰。综上可得Cu(NO_(3))_(2)的加入是会影响Au金纳米棒的生长,有利于块状金纳米材料的合成,这给块状金纳米颗粒的制备和生产应用提供了实验基础。Au nanorods were prepared by seed growth method by adjusting the concentration of Cu(NO_(3))_(2) in the growth solution.The samples were characterized by scanning electron microscopy(SEM)and UV absorption spectra.SEM images shown that the addition of Cu(NO_(3))_(2) made Au nanorods had two kinds:rod like and block like.With the increase of Cu(NO_(3))_(2) dosage,the amount of the rod like particles decreased and the block materials increased.When the dosage of Cu(NO_(3))_(2) was 3.0μL,the rod was the least.Combined with the UV absorption spectrum,it was found that the sample had only one absorption peak,and there was no longitudinal characteristic absorption peak of Au nanorods.In conclusion,the addition of Cu(NO_(3))_(2) will affect the growth of Au nanorods,which was conducive to the synthesis of bulk gold nanomaterials,which provided an experimental basis for the preparation and application of bulk gold nanoparticles.
