Characterization and Preparation of Glod Nanorods

Article Preview

Abstract:

Silver ions (Ag+) used as secondary ion, cetyl trimethyl ammonium bromide (CTAB) used as surfactant and ascorbic acid(AA) used as reducing agent, the gold(Au) nanorods were synthesized by seed-mediated growth method. The resulting substrates have been characterized by UV-vis spectroscopy. The law of Au nanorods growing was researched by controlling concentration of CTAB, Ag+, seed-fluid and AA. The results showed that the optimum reaction conditions are 0.10 M CTAB, 0.1×10-3 M Ag+, 0.0056×10-3 M AA, 0.48×10-6 M seed-fluid and system temperature 30°C.
