Synthesis of IR-emitting HgTe quantum dots using an ionic liquid-based tellurium precursor.

New scalable precursor chemistries for quantum dots are highly desirable and ionic liquids are viewed as an attractive alternative to existing solvents, as they are often considered green and recyclable. Here we report the synthesis of HgTe quantum dots with emission in the near-IR region using a phosphonium based ionic liquid, and without standard phosphine capping agents. In this communication, we highlight the use of an ionic liquid-based tellurium precursor in the synthesis of HgTe quantum dots.

量子点的新型可伸缩的前体化学分配非常可取，离子液体被视为现有溶剂的有吸引力替代品，因为它们通常被认为是绿色且可回收的。在这里，我们报告了使用基于磷的离子液体以及没有标准磷蛋白上限剂的HGTE量子点与近红外区域发射的合成。 在这种交流中，我们强调了在HGTE量子点的合成中使用基于离子液体的牙花饰前体的使用。
