Fabrication of 1D Microtubes of ZnS by Microwave Irradiation Method

1D tubes of ZnS were prepared by microwave irradiation process. The X-RD pattern indicated that as-prepared sample was hexagonal ZnS structure with cell constant a = 3.5277 A degrees and c = 5.79 A degrees. SEM observed the tubes-like structure having the length ranging from 10-20 mu m with the average diameter of 5 mu m and wall thickness of 1-2 mu m. The EDAX pattern exhibited the atomic percentage ratio of Zn : S = 59 : 41, indicating that it was rich in zinc. Effect of microwave power and exposure time on the growth process was investigated. It was revealed that the microwave power plays a vital role in determining the diameter of the tubes. This simple technique using a multimode microwave source may prove to be a potential tool for growing similar 1D structure of other -oxide, -sulphide, -selenide based compounds.
