基于Ostwald熟化机理，采用配体辅助溶剂热法成功合成了空心CdSe纳米球。以Cd（Ac）（2）和Se为前驱体，色氨酸为配体，在苯甲醇溶剂热条件下合成了空心CdSe纳米球。由此产生的中空结构由小的纳米碳硅石构建块组成。更重要的是，空心的CdSe纳米球可以被用作一个优秀的微波吸收剂的cm-和mm-波的吸收，这取决于吸收剂的厚度。
Hollow CdSe nanospheres were successfully synthesized by a ligand-assisted solvothermal method based on an Ostwald ripening mechanism. The hollow CdSe nanospheres were synthesized in benzyl alcohol under solvothermal conditions using Cd(Ac)(2) and Se as the precursors, and tryptophan as a ligand. The resulting hollow structures consisted of small nanocrystallite building blocks. More importantly, the hollow CdSe nanospheres could be used as an excellent microwave absorber for cm- and mm-wave absorption, depending on the thickness of the absorber.
