Abstract

Thin films of cadmium oxide CdO nanoparticles were prepared on glass substrates using pulse laser deposition technique (PLD). N:YAG laser is used with different laser energies (400,500,600,700)mJ, number of shots=100, when preparing all the thin films. The structure and optical characteristics were studied for these films. X-ray diffraction (XRD) results showed that all the prepared thin films were of a polycrystalline type and that the high and dominant crystalline levels were (111) at the angle (2θ =32.986). AFM results demonstrated a grain size of deposited films increase from (50.63-85)nm with laser energy from 400 to 700mJ. Also the absorbance spectrum increases from (0.53-1.45) with increasing laser energy, while the transmittance spectrum decreases with increasing laser energy of all prepared models so that transmittance is (26.53%) at the laser deposit energy (400mJ) until it becomes (1.70%) at the laser deposit energy (700mJ) and at the wavelength (550nm), as for the energy gap it decreases with increasing laser deposit energy and ranges from (2.3-2.5)eV.
