金纳米颗粒制备及其光学特性研究
Synthesis and Optical Characterizations of Gold Nanoparticles*
摘要
Abstract
By changing the volume ratio between seeds and growth solution and by introducing additional ions with seed-mediated growth method, rod and star-shaped gold nanoparticles were synthesized. First, the nanosphere particles colloid was working as the seed solution,and NaBH4 was introduced as reducing agent. Additional AgNO3 was also introduced as assistant reagent and CTAB as surfactant in growth solution. Different nanoparticles with different shapes were prepared using this method and characterized by UV-vis spectral and surface enhance Raman scattering. The results indicate that, star-shaped gold nanoparticles have the strongest SERS effect.关键词
