Abstract
A system for preparing of platinum-germanium alloy nanocrystals is provided herein, which comprises a first supply device for supplying platinum (II) iodide as the precursors of platinum and a second supply device for supplying germanium (IV) iodide as the precursors of germanium. The platinum (II) iodide, oleic acid (OA) and oleylamine (OLA) are added to the first supply device placed on a heating plate, and preheated for 30 minutes at 130 DEG C. Next, germanium (IV) iodide, oleic acid (OA) and oleylamine (OLA) are mixed and reheated to 130 DEG C. Then, the reaction temperature is heated up to 260 DEG C by a rate of 2 DEG C/min and once the temperature reached 260 DEG C, the first supply device was cooled instantly to room temperature. The nanoparticles (GePt3) could be obtained, whereas byproduct and unreacted precursors were discarded.
