| description | Colloidal AgBiS<sub>2</sub> nanocrystals (NCs) have attracted increasing attention as a near–infrared absorbent materials with non–toxic elements and a high absorption coefficient. In recent years, colloidal AgBiS<sub>2</sub> NCs have typically been synthesized via the hot injection method using hexamethyldisilathiane (TMS) as the sulfur source. However, the cost of TMS is one of the biggest obstacles to large–scale synthesis of colloidal AgBiS<sub>2</sub> NCs. Herein, we synthesized colloidal AgBiS<sub>2</sub> NCs using oleylamine@sulfur (OLA–S) solution as the sulfur source instead of TMS and optimized the synthesis conditions of colloidal AgBiS<sub>2</sub> NCs. By controlling the reaction injection temperature and the dosage of OLA–S, colloidal AgBiS<sub>2</sub> NCs with adjustable size can be synthesized. Compared with TMS–based colloidal AgBiS<sub>2</sub> NCs, the colloidal AgBiS<sub>2</sub> NCs based on OLA–S has good crystallinity and fewer defects. |
