Fast One-Step Synthesis of Anisotropic Silver Nanoparticles

The shape control of metal nanoparticles, along with the size, is critical for most their applications as they optical properties. Anisotropic nanoparticles show superior performance in a number compared to spherical ones. Shape usually achieved by two-step process, where first involves formation and second about actual transformation. In this paper, we report on fast facile synthesis silver nanoplates single step, involving laser ablation target liquid medium while exposed light irradiation hydrogen peroxide flow. We obtained anisotropic particles mixture shapes, 70–80 nm size 10–20 thickness, which showed plasmon sensitivity greater than 200 nm/RIU.
