ITO表面的CdS一维纳米结构的生长及表征

In the recent years, an amount of attentions have been attracted to the growth of one-dimensional CdS nanostructures because of their novel optical properties. For the application of CdS nanostructures in optoelectronic devices, it is desirable to synthesize the materials on the ITO glass substrate. In this letter, the orderly and well crystallized CdS nanostructures on the ITO glass substrate are demonstrated via Au nanoparticle-assisted thermal vapor deposition process. The morphology of CdS nanostructures are optimized by controlling the growth parameters in terms of the flow rate of carrier gas, pressure and substrate position in the furnace, etc. The growth mechanism of CdS nanotructures on ITO substrate is analyzed based on the characterization of SEM, TEM and EDX.
