In the present work, we studied a unique and facile method for the drastic structural transformation of hydrophobic small CdE (E = S, Se, Te) nanoparticles into large, high-quality pencil-shaped nanoparticles through an Ostwald ripening process induced by Cl(-) and surfactants (oleic acid and oleylamine). This study revealed that Cl(-) is the effective anion for the controlled structural transformation of CdE nanoparticles. This transformation reaction can be readily extended to the formation of various functional materials.
在本工作中，我们研究了一种独特且简便的方法，通过 Cl(-) 和表面活性剂（油酸和油胺）引发的奥斯特瓦尔德熟化过程，可将疏水性小的 CdE（E = S、Se、Te）纳米颗粒剧烈转化为大尺寸、高质量的铅笔形纳米颗粒。研究表明，Cl(-) 是控制 CdE 纳米颗粒结构转化的有效阴离子。这种转化反应可容易地扩展到各种功能材料的形成。
