Optimum Conditions of Gold Nanorods Preparation by Seed-Mediated Growth Method

Abstract

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
