Structural, morphological and optical properties of CdO nanostructures synthesized by chemical bath deposition method

In the present work, we have successfully synthesized CdO nanostructures with various molar concentrations by a two-step chemical method. The crystal structure of our nanostructured CdO thin films is cubic phase while the microscopic images show the formation of nanoparticles, spindles, and coconut fiber bark shaped CdO nanostructured films. These different structures were achieved merely by controlling the molar concentration of cadmium nitrate tetrahydrate and hexamethylenetetramine. The size of the CdO nanostructure slightly increases monotonically with molar concentration. Our chemical synthesis approach is inexpensive, reproducible and scalable.
