Synthesis of Silver Nanoplates by Reducing Silver Nitrate with Poly(vinyl pyrrolidone) in N-Methyl-Pyrrolidone |
| 초록 |
The hydroxyl end groups of PVP have been shown to serve as a mild reductant for the kinetically controlled synthesis of Ag nanoplates. In this study, we report a simple approach to the synthesis of Ag nanoplates with controlled shapes by reducing silver nitrate (AgNO3) with poly(vinyl pyrrolidone) (PVP) in a N-methyl-pyrrolidone (NMP). Ag nanoplates with tunable size and aspect ratio could be formed with high yields in a kinetically controlled synthesis using NMP as the reaction medium. The reaction time and weight ratio of PVP to AgNO3 could both be adjusted to permit the shape-controlled synthesis of Ag nanoplates, that is, with control over the nanoplate size and aspect ratio. Shape control permitted tuning of the localized surface plasmon resonance (LSPR) peaks of these Ag nanoplates over the visible and near-IR regions. |
