摘要/Abstract

摘要： 目的：利用种子生长法制备金纳米棒，探索最佳制备条件。方法：通过对种子生长法中增长媒质的不同成分浓度比例及生长温度的控制聚合成形貌特征不同的金纳米棒，并利用紫外分光光度计进行测定。结果：通过对GNRs在制备过程中还原剂、活性剂、温度等条件的优化，发现在增长媒质中CTAB的最佳浓度为0.095 mol/L，AA的最佳浓度为0.640 mmol/L，AgNO3的最佳浓度为72 mmol/L，种子的最佳生长温度为28 °C。结论：本实验系统研究了金纳米棒聚合过程中的生长机理和最佳实验条件，合成了具有所需的光学性质的金纳米棒。

Abstract: Objective: To explore gold Nanorods preparation with best conditions by seed-mediated growth method. Methods: To synthesize different morphological characteristics of gold Nanoparticles by controlling the concentration ratio of different compositions and the growth temperature, and the synthesized gold Nanoparticles were characterized by UV- vis spectroscopy. Results: By optimizing the reducing agent, surfactant, and temperature, etc，the best concentration of CTAB was 0.095 mol/L，of AA was 0.640 mmol/L，and of AgNO3 was 72 mmol/L. The best temperature was 28°C. Conclusion: The gold Nanoparticles growth mechanism in the process of polymerization and the best experimental conditions were studied，and the optical properties of GNRs were successfully prepared.

Key words: gold Nanoparticles, growth mechanism, optimize
