Morphological development of CdSe_0.6Te_0.4 nanostructures by simple preparative parameters in electrochemical method and their subsequent influence on photoelectrochemical cell

Cadmium seleno–telluride (CdSe_0.6Te_0.4) ternary thin films were deposited on the stainless steel and fluorine doped tin oxide glass substrates using galvanostatic mode at different bath concentrations of CdSO₄. CdSe_0.6Te_0.4 thin films were characterized using X-ray diffraction (XRD), UV–Vis spectroscopy, and field emission scanning electron microscopy (FE-SEM), and contact angle measurements. XRD patterns revealed the formation of the crystalline CdSe_0.6Te_0.4 nanomaterial’s having hexagonal crystal structure. FE-SEM micrographs show the formation of different kind of nanostructure morphologies, such as nanoparticle-like, nanonest-like, and nanoflower. The optical study suggests range of variation in the band gap of CdSe_0.6Te_0.4 thin films. The electrochemical performance for the interconnected nanoparticle and nanonest, nanoflowers of the CdSe_0.6Te_0.4 electrode were found to be, about 0.61, 0.81 and 0.54%, respectively.
