In the present paper, the method of electrochemical deposition was employed for the growth of CdSe structures with various morphologies from thin film to self-assembled crystalline nanowires. CdSe films electrodeposited from aqueous solutions on indium tin oxide (ITO) coated glass substrates were characterized for their structural, morphological, compositional and electrochemical properties. Influence of composition of electrolyte, pH and deposition time on composition, morphology and crystallinity of the deposited films was studied. The scanning electron microscopy (SEM) study of CdSe structures shows the difference of the morphology from thin films and spherical grains to 200 nm-long self-assembled nanowires depending on conditions of the deposition.
