摘　　要：先以氯金酸和硼氢化钠为原料合成直径为14 nm左右的金种子,然后在完全相同条件下的生长溶液中加入不同数量的金种子溶液以生长形成金纳米棒。结果表明,随种子用量增加,金纳米棒纵向吸收峰的波长增加,平均长径比从1.3增加到4.0。The gold seeds with average diameter of 14 nm are prepared from HAuCl4 and NaBH4,then the gold nanorods are fabricated by different quantity seed solutions added to the growth solution. The results show that lengthways absorbance spectra of gold nanoreds increass with increasing amount of added gold seed. The average aspect ratio of them can be increased from 1.3 to 4.0.
