Study of the optical proprieties of copper oxide nanoparticles prepared by PLD method


Nano CuO thin films on glass substrates were prepared at a constant temperature of (300°C), by pulsed laser deposition (PLD) using Nd:YAG laser at 1064 nm wavelength and five deposition energies (400, 500, 600, 700 and 800 mJ) with fixed pulses (300 pulse and 6 Hz) was used on the properties of CuO films. CuO nanoparticles were deposited on glass substrates to study optical properties and formed thin films of thickness (200 nm).CuO thin flims were characterized by X-ray diffraction (XRD) measurements have shown that the polycrystalline CuO prepared at laser energies , includes optical transmittance and absorption measurements and energy gap of these films.
