【 摘 要 】

Mercury doped zinc oxide (ZnO:Hg) thin films deposited on glass substrate at 400 °C, prepared by Chemical Spry Pyrolysis (CSP) technique for (3,6, and 9)% doping concentrations, structural properties has been measured by X-Ray Diffraction (XRD) which reveals the structure of (ZnO:Hg) thin films have been found the hexagonal wurtzite structure, crystallite size increases for ZnO:Hg(3%) then decreases with the increase of doping concentration. Atomic Force Microscope (AFM) used to measure granularity distribution, roughness and grain size. Increase of mercury doping leads to increasing of sensitivity for CO2 gas.
