在目前的工作中，我们研究了一种独特的和简便的方法，通过Ostwald熟化过程诱导的Cl-和表面活性剂（油酸和油胺）的疏水性小的CdTe（E = S，Se，Te）纳米粒子到大的，高品质的纳米粒子的急剧结构转变。本研究表明，氯离子是有效的阴离子的控制结构的转换的镉纳米粒子。这种转化反应可以很容易地扩展到各种功能材料的形成。
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.
