Real time imaging of the growth of silver ribbons by evanescent wave microscopy†
Abstract
Real time visualization of the in situ growth of ∼40 μm long high aspect ratio silver ribbons, synthesized by template-free galvanic displacement using ∼100 nm Cu particles and Ag ions in aqueous conditions, is demonstrated using evanescent wave microscopy. The observed growth rate from several ribbons is 1.5 ± 0.5 μm s−1.
