The properties of thin Y2O3 films grown using an in situ ultraviolet (UV)-assisted pulsed laser deposition (PLD) technique were studied. With respect to Y2O3 films grown by conventional PLD under similar conditions but without UV illumination, the UVPLD-grown films exhibited better structural and optical properties, especially for lower substrate temperatures, from 340 to 400 °C. These layers were highly crystalline and textured along the (111) direction, and their refractive index values were similar to those of reference Y2O3 layers. They also exhibited a better stoichiometry and contained less physisorbed oxygen than the conventional PLD-grown layers.

Structural and optical properties of CdO and CdO0.99Cu0.01 thinfilms were prepared in this work. Cadmium Oxide (CdO) andCdO0.99Cu0.01semiconducting films are deposited on glass substratesby using pulsed laser deposition method (PLD) using SHG with QswitchedNd:YAG pulsed laser operation at 1064nm in 6x10-2 mbarvacuum condition and frequency 6 Hz. CdO and CdO0.99Cu0.01 thinfilms annealed at 550 C̊ for 12 min. The crystalline structure wasstudied by X-ray diffraction (XRD) method and atomic forcemicroscope (AFM). It shows that the films are polycrystalline.Optical properties of thin films were analyzed. The direct band gapenergy of CdO and CdO0.99Cu0.01 thin films were determined from(αhυ)1/2 vs. photon energy curve and found to be 2.3 eV for CdO thinfilm, comparing with that the CdO0.99Cu0.01film which found to be2.2eV. The electrical measurements shows that the conductivity andmobility of the charge carriers increase when Cu doped CdO.
