Shape, size and configuration tuning in ZnSe nanostructure thin films through deposition temperature, pH controlling and deposition time

Abstract

We investigate the deposition temperature, pH and deposition time that govern evolution of the nanoparticle shape, size and density of ZnSe nanoparticle arrays. The nanoparticle arrays were grown on glass substrate using a facile chemical bath deposition method. The samples were also characterized by absorbance spectra for energy band gap determination and scanning electron microscopy. In comparison to other similar works, our method is simple, low cost and can be easily controlled. We find that temperature helps to tailoring the nanoparticle shape and has a critical role in comparison with other parameters such as pH and deposition time.
