单分散的氧化锌胶体纳米晶簇（CNCs）通过一种快速的微波多元醇法合成。通过改变锌配合物前体的量，簇的尺寸可在57到274纳米之间调节。独特的二级纳米结构、纳米微晶间结构以及大的内表面的结合，使得这些氧化锌纳米晶簇成为湿度传感等应用的理想候选材料。
Monodisperse ZnO colloidal nanocrystal clusters (CNCs) are synthesized through a rapid microwave-polyol process. The size of the clusters is tunable from 57 to 274 nm by varying the amount of Zn-complex precursors. The combination of unique secondary nanostructures, inter-nanocrystallites, and large internal surfaces make these ZnO CNCs ideal candidates for applications such as humidity sensing.
