我们报告了使用乙烯碳二亚胺偶联程序（EDC）控制合成多壁碳纳米管-量子点（CNT-QD）异质结。硫醇稳定的ZnS-帽的CdSe量子点含有胺端基（QD-NH 2）与酸处理的多壁碳纳米管（MWCNT）的共轭长度范围从400 nm到4 μ m。扫描和透射电子显微镜用于表征缀合过程。
We report the controlled synthesis of multiwalled carbon nanotube-quantum dot (CNT-QD) heterojunctions using the ethylene carbodiimide coupling procedure (EDC). Thiol-stabilized ZnS-capped CdSe quantum dots containing amine terminal groups (QD-NH2) were conjugated with acid-treated multiwalled carbon nanotubes (MWCNT) ranging from 400 nm to 4 mum in length. Scanning and transmission electron microscopy were used to characterize the conjugation process.
