Systematic Study of Triangular Silver Nanoplates : Green Synthesis and Sensing Applications |
| 초록 |
Silver nanoplates were synthesized by one-pot green synthesis method using the coordination of ligands to Ag cations with a high yield. We investigated the chemical stability and degradation behaviour of the Ag nanoplates upon exposure potassium persulfate. When the Ag nanoplates were aged with potassium persulfate, the shape evolution of Ag nanoplates was found to depend on the external temperature, and the Ag nanoplate solutions showed different final colors when different external temperatures were applied. These results can be applied to the colorimetric sensing of the temperature history. Secondly, we designed a system that uses the color and spectral changes associated with the spontaneous rounding of the sharp corners of triangular Ag nanoplates exposed to bromide ions to quantify the water fraction in water-ethanol mixtures. This sensing platform was successfully applied to the quantification of water in water-ethanol mixtures having any water volume fraction (from 0 to 1.0). |
