Most previous studies involving chemical reduction methods reported that Ag nanoplates underwent lateral growth, but vertical growth that could increase the thickness of the Ag nanoplates was not observed previously in single-step synthesis approaches. Here, we describe a simple approach to the synthesis of Ag nanoplates with well-controlled shapes in which halide ions(including Cl−, Br−, and I−) guide the well-defined kinetically controlled synthetic route. This single-step procedure is quite simple, and the Ag nanoplate reaction yield (the percentage of plates present among the products) was very high. In this method, the halide ions promoted vertical growth in the nanoplate structure, resulting in small thick nanoplates. These morphological changes also allow us to finely tune the LSPR peaks of the nanoplates from the visible region to the NIR region |
