Abstract

The present work demonstrates a synthesis of nanocrystalline thin films of cadmium selenide (CdSe) using photo-assisted chemical bath deposition (CBD) techniques at room temperature. The structure of the CdSe films deposited under different coloured illumination was confirmed by X-ray diffraction and the effect of the monochromatic light on the growth rate was observed. The secondary electron microscopy (SEM) result demonstrated different morphology of the different films' surfaces, such as granular spherical, cauliflower, fiber, or wire, with a variety of porosity that was achieved by a simpler photochemical route. The results obtained from UV-visible spectra showed a decrease in the optical bandgap from 2 to 1.8 eV.
