X-ray diffraction (XRD) patterns confirmed the nanocrystalline cubic CdO phase formation. The intensity of XRD peaks increases with the increase in substrate temperature and better crystallinity takes place at higher temperature. The morphology of deposited films were characterized by scanning electron microscope (SEM) and atomic force microscope (AFM); with increasing substrate temperature, both the grain size and surface roughness increase .The grain size value (12,18,47 nm) and rms roughness values were 63.3, 98.8 and 138.4 nm for thin films deposited at 100 , 200 and 300ºC respectively. UV–Vis spectrophotometric measurement showed high transparency (nearly 88 % in the wavelength range 500–900 nm) of the CdO thin film with a direct allowed band gap value lying in the range 2.81–3.7eV}, keywords = {Nanostructure Cadmium oxide,Transparent conducting oxides,PLD}, url = {https://etj.uotechnology.edu.iq/article_25874.html}, eprint = {https://etj.uotechnology.edu.iq/article_25874_1c999053af18abf7dea14af49f12d6e9.pdf} }
