A simple hydrothermal route to fabrication of single-crystalline silver nanoplates using poly(vinyl pyrrolidone)

Abstract

Single-crystalline silver nanoplates with an average in-plane dimension and thickness of about 700 and 25 nm, respectively, were fabricated on a large scale in aqueous poly(vinyl pyrrolidone)/AgNO₃ solution by a simple one-step hydrothermal method. In this process, poly(vinyl pyrrolidone) (PVP) acts as both reducing agent and shape-directing agent. SAED and XRD measurements reveal that the growth of silver nanoplates is mainly dominated by (111) facets.

Keywords
