A method for synthesizing a metal chalcogenide nanocrystal (NC) material includes reacting a metal material and an ammonium chalcogenide material in an organic solvent material. The method provides that the metal chalcogenide nanocrystal material may be synthesized by a heating-up method at large scale (i.e., greater than 30 grams). Ammonium chalcogenide salts exhibit high reactivity and metal chalcogenide nanocrystals can be synthesized at low temperatures (i.e., less than 200° C.) with high conversion yields (i.e., greater than 90 percent).
一种合成金属硫属族纳米晶体(NC)材料的方法包括在有机溶剂材料中反应金属材料和铵硫属化物材料。该方法提供了在大规模(即大于30克)下,可以通过加热方法合成金属硫属族纳米晶体材料。铵硫属化物盐具有高反应性,金属硫属族纳米晶体可以在低温(即小于200°C)下高转化收率(即大于90%)地合成。
