| 摘要: 本文报道了一个新颖的酸化方法在室温下于聚丙烯酸及其钠盐形成的缓冲体系中制得直径为50nm、长为5μm的单晶硒纳米线。使用此法可将硒纳米线的成核及生长时间缩短为3h。一系列表征结果证明利用这一简单有效的方法在短时间内可成功地生长出均一尺寸的硒纳米线。 |

| Abstract: A novel acidification approach has been used for the preparation of Se nanowires with the diameter of 50nm and length of 5μm in poly(acrylic acid)- poly(sodium acrylic) buffer system at room temperature. The whole time of nucleation and growth of Se nanowires were cut short remarkably to 3h under ambient conditions. The characteristic results demonstrate that it is successful to adopt this convenient and effective acidification method to grow uniform Se nanowires in a rather short time in air at room temperature. |
