One-pot synthesis of silver nanoshells with near-infrared extinction by a thiocyanate-assisted approach†
Abstract
We report the one-pot synthesis of silver nanoshells with near-infrared extinction assisted by thiocyanate. Our protocol is based on sequential addition of NaSCN and NaBH4 to an aqueous solution of AgNO3 followed by addition of a water-soluble thiol, affording the silver nanoshell with an extinction band around 600–700 nm.
