【 摘 要 】

Silver oxide AgO has been iduced by Pulse Laser Ablation PLA in methanol at 600 pulses and 600 mJ as laser energy .The structural, morphological, optical and properties of the silver oxide AgO thin film have been studied .The surface morphology, crystallite size, microstrain and dislocation density were studied using X- ray diffraction (XRD) .The results shows that the narrow and sharp peaks at (112) and (222) plans were dominated for the crystal quality of the AgO film. Transmittance and absorption data have been used to calculate the spectral variation of their optical constants. The optical results show that the films have a band gap of 3.5 eV and AgOfilms transmit in the UV and visible regions.
