Forming spherical gold nanoparticles from polymorphic nanoparticles using a single laser pulse
Source abstract
Abstract
A method is presented for using a single laser pulse to transform polymorphic polycrystalline gold nanoparticles (Au NPs) into crystalline nanospheres. Transmission electron microscope analysis of the nominally 60-nm-diameter Au NP starting material and the product suspension confirms the production of slightly smaller particles that exhibit greater crystallinity and feature reduced caliper diameter aspect ratios and anisotropy. Centrifugation followed by ultrasonic resuspension into citrate solution separates the nanospheres from the <15 nm ablation fragments, providing a route to monodisperse spherical crystalline Au NPs.
