| In this work, we investigated the effects of the ambient liquid medium on the size, optical and stability properties of gold nanoparticles synthesized by electrical explosion of wire. The explosion process was carried out in deionized water, cetyl trimethyl ammonium bromide (CTAB), sodium dodecylbenzenesulfonate (SDBS) and tween 20 (TW20) solutions. Particle size and shape of nanoparticles were observed by transmission electron microscope. Optical absorption spectrum was employed for characterization of optical properties. In TW20 and CTAB solution, particles were in nearly spherical shape. In water and SDBS solution, the particles formed to a chain across particles. The wavelengths of optical absorption peak were 525, 526, 530, 532 nm in SDBS, TW20, CTAB and water respectively. Stability of gold suspension was estimated by multiple light scattering using Turbiscan lab machine. Gold suspension in TW20 showed the best stability in four samples. |
